BU Seminar: Seamless, Unified Operational Visibility and Analytics Designed for Cloud

I will be giving a talk on our recent work on cloud monitoring & operational analytics in Boston Univ. next week. The details are below. I am hoping to add what I learn from the day’s discusions later as well.

Seamless, Unified Operational Visibility and Analytics Designed for Cloud

Emerging cloud services allow users to define and provision complex, distributed systems with unprecedented simplicity and agility. With the push of a button entire stacks of software can be instantiated within minutes with various configurations and customizations. Automation, continuous integration and delivery further simplify the entire lifecycle management of modern born-on-the-cloud applications. These advances also bring in additional research challenges and opportunities for cloud. Operational visibility into the complex, distributed user applications, cloud runtimes and the underlying infrastructure is becoming a persistent pain point for both the end users and the service/platform providers. As the system and configuration complexity grows, data-driven operational analytics for security, compliance, configuration and resource management are becoming key areas of interest. In both cases—of operational visibility and analytics—existing, traditional solutions are either ineffective or insufficient. Their assumptions are based on a different era of computing that no longer applies, with long-running, dedicated systems that can tolerate ample configuration times and resource overheads, and where it is common practice to push monitoring and analytics burden to the end user context. In this talk, I propose a fundamentally-different approach for designing seamless, unified and deep operational visibility and analytics services in the cloud. I first present Agentless System Crawler, a cloud-native framework, which leverages cloud, virtualization and containerization abstractions to provide complete visibility into running entities in the cloud, without modifying, instrumenting or accessing into the end user context. Our approach with crawlers is based on introspection without intrusion, and as-a-service without necessitating guest cooperation. I demonstrate how we use VM introspection and container namespace mapping techniques to provide a “touchless”, “out-of-band” and “always-on” cloud operational visibility service that is built into the platform. Cloud users simply register for this service, without worrying about the plumbing, overheads or side effects of gaining visibility into their environments. Cloud operators can leverage this approach to provide deeper operational insights without intervening with user environment, thus enabling a new set of cloud operational analytics as a service that are always on and available with the push of a button. In the second part of this talk, I discuss how we leverage this seamless, deep visibility today for building cloud-native operational analytics services for security, compliance, system discovery and misconfiguration analysis. Last, I present some of the open problems and some of our upcoming research directions.

Try It:

Discussed Open Problems as Promised:

  • Truly Seamless OpVis: No performance impact (~/~) + Absolutely no side effects (+/-)
  • Extensibility and configurability: Deep visibility into system, application and infra
  • Scale out across runtimes and scale up to many instances; challenges & limits
  • How do you design DDOS-mitigation/admission-control/fair sharing in this model of built-in service
  • Privacy and data sensitivity with Ops data analytics
  • Piecemeal analytics/security solutions –> Cloud analytics/security roadmap
  • Rules/annotators –> Actually smart analytics that learn
  • good and bad configs for security, performance, availability, etc.
  • Cross-silo analytics across Time, Space, Dev/Ops [CloudSight Dream]

Additional Points from Discussion:

  • Decoupling data for security and privacy concerns: Crawl system data and not user data. Give user the flexibility to choose what is exposed and what is not. We should find out better ways of controlling what is visible to any monalytcis system. Whether agent-based or agentless.
  • Is out-of-band approach really secure: good point on never enough security, and centralized point of entry. VMs, vs. containers vs. unikernels.
  • TBC


On a somewhat unrelated note, Docker also released Docker DC  for on prem containers svc.

Today we are excited to announce the availability of Docker Datacenter (DDC), an integrated, end-to-end platform for application development and management at any scale. The enterprise-ready solution includes: Docker Universal Control Plane, Docker Trusted Registry and embedded support for Docker Engine and Swarm.

Yes. they were cloudant. they were office neighbors. runkeeper and cloudant. runkeeper used cloudant for data mgmt.

They pulled 3M routes of users. and use that find popular segments and as rec wngine. Awesome example. data is king. used graphdb svc for this.

They did sth in munich w dashdb.
from routes to watson analytics, twitter, personality insights,…
runkeeper ceo said they wanna be a “trusted advisor”. i think we found Jims soulmate. Enphasizing data, personilzed svc.

Simon will go to namibia to run alone in desert. bmix garage will helps him.

CMU SDI/ISTC Seminar: Agentless, Near-realtime VM Introspection in Origami

One of my earlier talks on agentless, introspection-based monitoring for VMs. It is interesting how long we have been pushing on this, and how recent containerization business made these ideas resonate more. I just copied from the SDI/ISTC Seminar Series for nostalgia:

DATE: Thursday, January 31, 2013
TIME: Noon – 1:00 pm
PLACE: Gates 8102
SPEAKER: Canturk Isci, IBM TJ Watson

TITLE: Agentless, Near-realtime VM Introspection in Origami

Enterprise data centers continue to embrace virtualization and cloud computing technologies due to their dramatic benefits for simplifying and streamlining system provisioning and management, as well as to improve overall resource use efficiency of the underlying hardware infrastructure via virtual machine (VM) consolidation and dynamic, distributed resource management. As virtualization and cloud automation has made it cheap and simple to create, deploy and recycle VMs on a large scale, modern data centers have become much more dynamic environments than they were a few years ago. This is creating new challenges for routine maintenance operations like security and compliance scans, that continue rely on a decades-old model based on in-VM monitoring agents and rule-driven analytics. When machines become transient and fungible resources, this model breaks down, resulting in increasing operational cost and risk.

In this talk we present a different approach to maintaining a large-scale dynamic data center. We show that out-of-VM monitoring agents can approach the data fidelity and real-time view as in-VM monitoring agents. Using this foundation we show how systems can be viewed as documents, enabling data mining and ad-hoc analytics techniques to be exploited for data center maintenance operations. These technologies are under development as part of the Origami system, an ambitious project to treat systems as data, and transform the way dynamic Cloud data centers are managed.

Mini NY Trip Log

A simple log of my trip around NY/NJ early Dec 2015. Originally plans were  for a longer break going somewhere. It had to be delayed from Friday to the following Monday and had to be back by Thursday for Family vacation. So I decided to travel local on a mini trip. The idea was to simply explore locations from map without plans. I picked going North and got started. I did not go much far as i hoped, but did bunch of unglamorous stops along the way, which was fun.

Day 1:
Getting out of NJ was interesting. It is very industrial and polluted and worn down at places. Bunch of insustrial ways, local roads. One of my best views was from Oradell Reservuar and through a random walk into a United Water way. I end up going more into green areas by the water. Everywhere is golf courses and country clubs. You will be prosecuted if you enter apparently.

My early NJ stops:

Apparently there is a Hackensack Green Trail:


In Ridgefield park. There is sth called Indian Pond. One Side of it:

The other side: 

Next, moving around NJ, ended up by the Oradell reservoir via the random turn into United Water: 

 This was the best hike of the day. Very nice view and path.

From here went to Lake Tappan. It had  gorgeous view but arrived too late. View from the bridge:

After Tappan, kept North, towards Nanuet and it was time to test out tonite booking.

The Booking:

I was interested in how this turns out. I wanted to experiment w bunch of options to see if they made a difference. Here is my list:

I was expecting some magic there but the big ones all ended up fairly similar:, Hotels, Booking Now, TripAdvisor, Priceline:


Trip Advisor:

Booking Now: also has a nice landing page form for booking tonight, nearby: 

I ended up booking from Booking Now. Because it just booked it while i was expecting a confirmation w tax included. Oh well..

Now some of the others did poorly. I was curious about HotelTonight but i think its magic is not there for me:

Kayak also was not that great for last minute. But that is not their prime use case anyway.  

So overall, swinging thru 8 apps was in many ways a waste of time, no magic w HT, and i just booked the first hotel i liked w the first price i saw from Hotels. I still used TripAdvisor for reviews. We will give all another shot.

Now though, this last bit was scary, from Google Maps–it already knows😱

Overall Trip Day 1 from LiveTrekker:

and highlights from iOS Photos:

Keep on North tomorrrow.

Day 2:

It ended up not the way I hoped. I wanted to go to Hudson side, revisit some high grounds i had passed thru before and then cut off to few parks up north and then go to Harriman side. It turned out i did one whole loop.

First stop Nyack and Grandview. I wanted to go back here for a while. This is a place w a tiny road that hardly anyone passes, great houses w crazy views of Hudson and Tappan Zee from up top. I parked and walked all thru it by myself. Barely anyone around. Hard to get a great view unless you are trespassing some of the houses.

One side of road:
The other side is forest:

On my way back, I thought I lost my car; I had just left it on the roadside, so maybe towed. But eventually found it. Waiting there by itself:

Once I found the car, next was straight North to first a quick stop at Nyack College, then to Rockland Lake, which turned out to be awesome. We should come back here summer for bbq w Seleno!! Because I spent so much time here, could not make it to Harriman before sunset.

View of lake, swans, geese and ducks:

After the lake, trip around Hook Mtn into the Hudson shore. This was the best part.

Waterside landing

I watched trains on Westchester side and then walked to the end of the path along the coast. Tappan Zee is on the horizon.

Walked back out after some time and made way to Conger and then DeForest. Conger was a great sight.  

After the driving tour around DeForest, took up NW and ran into Lake Lucie. It is a private community? Then around 5:30 while it was already way dark, looked for a booking. Amusing problem: the Haverstraw et al. area is like devoid of much lodging. Options were: back to Nanuet vs. Nyack area. So there I ended up back in the same hotel. Here is the entire loop:


After some searching. Same hotel turned out to be the best cost/benefit. This time though, Priceline was the choice $10 cheaper from Hotels and Booking.

Tomorrow, it is Harriman time, I am hoping to cross North and find lodging up top around Woodbury. Here is to hoping.

Day 3:

I am tired after a 5hr hike in Harriman State Park and a drive North to Windsor thru Seven Lakes and Bear Mountain. Honestly, I did some prep and planning this time to make sure i find my way back out. It was well worth it. I arrived Harriman at 10:20 and finished the hike around 15:30. I actually followed the “Raccoon Brook Hills Trail/Pine Meadow Lake/Diamond Mountain Loop” in here, which was awesome directions:

It was not simple walking as i hoped, but I feel good after two summits. The combos and switching of trails was hard to keep up. The trail pdf map was absolutely helpful.  This is what i followed:

 I traversed red -> white -> black  -> yellow -> gray -> red -> yellow -> orange -> white -> yellow -> red. W/o the detailed directions, very tough to keep track. I lost track a couple of times and tracked back. Looking for the next blaze. Also, the directions on Safari disappeared when i started to lose coverage:

This would suck and hopefully pocket was to the rescue, where i saved the same:

Trail Started at Reeves Brook info center here: 

Took the red on white by the brook: 

switched to white (Katiaka)

Switched to black on white (racoon) and climbed some tough rocks: 

Reached the top: 

Had some time for food and view here. Also checked all email and msgs. It has been great, the wntire hike i only saw a handful folks and it was just me pretty much the entire time. By myself on the summit as well. Then back down. Happy to finally see the lake. It was a short switch to yellow on white and then grey dirt road to beautiful Pine Meadow Lake. I was at this point thinking they should have called the trails based on their colors so i shouldnt memorize two things. Then it dawned on me “poached egg” and “racoon”:).

The lake was great for some lunch and pics. One more couple on another side of lake, and that was it.

After the lake break, i assume the hard part was over. Not really. The red and then yellow up the Diamond Mtn. This was over the rocks pretty much and lost track of signs couple of times. One more revelation at this time, looking for blazes: I understood literally what “trailblazer” means. Eventually made it to top.

Then it was a climb down w orange and that was fun.

Then jumping along big boulders along white. I know why it is called “stony” brook. Then it was an easy hike from yellow and back to red and back to parking.

Some good advise back at the info place.  

5 hours gone and it was already past 3:30. I drove to Lake Welsh and then Lake Sakunega.

Continued North on Seven Lakes. Some great views on the way.  

Eventually past Doodletown on 9W, i started to have coverage again. Stopped in a Holiday Inn Express to book stay elsewhere:).

This is my entire trip, courtesy of LiveTrekker.

One more key credit of the day goes to my APC mobile battery. I drained the entire thing today, and i would be screwed big time w/0 phone.

Booking: It is getting less interesting. All three of Booking, Hotels, Priceline were close. Hotels won this time by a couple bucks.

Big G is scary again:

I walked to a pub for food and here is a view from my accoms tonite:

Tomorrow is return day:( but there is Beacon, Andrew’s Nose and Bear Mtn Bridge in menu.

Day 4:

My last day turned out to be great. I had an early morning stop at what is called Kowawase Unique Area. Small park w a great view:

I spent a short while here w views of Hudson and Storm King(?) toward South and the Newburgh-Beacon Bridge at North.

After this I started North, crossed Newburgh-Beacon Bridge and stopped in Beacon. They had couple of great riverside spots near the station for a quick walk.

 After that I also made a stop at Dia, which was closed.

Then it was onto South on the Beacon side of Hudson, driving thru 9D.

First stop on the way was Breakneck Ridge. I did a 10 min hike here but no more.

Then it was all the way down to Anthony’s Nose, which certainly was the highlight of the day.

I parked next to 9D, right before the Apalachian Trail sign. The perks of a coldish weekday, no crowds, or literally noone. 
I climbed part of the Apalachian Trail (yes!) to Camp Smith trail and reached the summit. The Apalachian part is steep w rock-stairs. So I broke some sweat. Two somewhat obvious revelations: I am out of shape; and I should not be climbing w my glasses, they keep falling off. This was a great reference for this Path:

The view up top was great.

I had some lunch overlooking Hudson, Bear Mtn and Bear Mtn Bridge

And phone signals were working. For better ir worse, I was reminded of real world right in the middle of things.

After these I took the same way back down, which was relatively quick. On the last part of the AT, I took a shortcut down, which got me onto 9D right here:

After a short walk roadside, my car was waiting for me in the horizon

Next stop was crossing the Bear Mtn Bridge and Bear Mtn Park. I spent some time there looking back at Anthony’s Nose, then started up another part of the Apalachian trail, which is basically climbing a 1000 steps onto Bear Mtn. I stopped halfway at an opening, had some snacks, looked at the view and eventually decided to return back to the lakeside before dark. The view from the trail, as high as i got:

After this, i had a few mins to walk around lake Hessian and a get a great view of Anthony’s Nose.

I stopped by the park next to the inn, had a some drink against Bear Mtn, and that was it. Next was All the way back to home, which ironically was quicker than my commute.

All in all this was a fantastic mini trip w a lot of time away from most things, but nature. Absolutely to be continued some day.

Notekeeping with WordPress

This was the first time i used WP for notekeeping in a conference. More recently i was flipping between Evernote, Notes and PlainText. I liked Evernote for being able to post anything, but the “upload everything after each edit” behavior was getting annoying as i was reaching my free quota fairly quickly. 

So i tried Notes and PlainText, but too many pics etc. make these unideal.  

Then i went to my latest love affair, Slack, and created a channel for the conf. That sounded like a good idea, but i the messaging platform view is really rough for this stuff. What is worse is, when i want modify txt, insert images, it is too difficult. So, obvious revelation: Slack is good for “append” and bad for “insert”:). No offense intended 😊

WP was just a trial. I did not expect it to be fast and easy to use, but it turns out a great way to do this thing. I took all my DockerCon notes live on WP on mobile and it was easy and fun. Hosting your own WP helps greatly, so i have control over who sees the content and how. 

One more great benefit: previously i would convert my Evernotes to html and post to my web for sharing. Now, all i do is point to my blog and folks can access while i type even. I would say this is good soln. The biggest enabler is the great, reliable mobile app👍.


Could not pay sufficient attention to all:

1. Container Migration – Mantika

2. Unikernel in docker – Anil…

3. Minecraft by docker folks

Very cool. ctrl containers from minecraft. we really needed this feature.


jean-tiare From OVH,

talks about introspection, how to run binary incontainer. need to get charts. 


GRREAT SIMPLE description of what a container is and how you become one.

how to enter a container

setns, execv

What about host binaries:

easy -> patch; hard -> auto code rewrite;


Trace, mess w process, interact w process (like gdb)

what he does:

run setns and ptrace

Very good talk on namespace jumping. very similar to what we are already doing w crawler w static binary. So: good /.

A lot more wxamples and demos. Get the video and slides here.

Code Also in github.

(Social Bookmarks + Social Share Counts) / Read It Later

In Research we have the chance evaluate our projects in multiple dimensions including science, image, product, open source, and service impact among others. I have participated in this process in various roles over the past few years, and have learned a lot of interesting things first as the outside reviewer of some of these projects and lately have been preparing the evaluations of my team projects.

Science Impact: Last year I was looking into the science impact of some of our projects, and it seemed rather archaic to go through some of our papers, and add them title by title and citation by citation to a spreadsheet or doc, which has been kind of the common practice and would look like something like this:

Screen Shot 2015-08-11 at 10.05.35 PM

It was relatively easy and painless to create a dynamic and online version of this with Google Scholar. I simply created a pseudo GMail user, and then searched and colected relevant references from different contributors of the project. It is a somewhat non-standard use of Scholar, because unlike my personal Scholar page that has ALL citations that ALL include ME, this was hand picked subset of papers from multiple authors. So there was some customization involved. The end result of this looked much better, and most importantly it is dynamic as it continues to update itself:

Scholar Page for DCEM ProjectI did not have much to do with this page since its creation, and it is pretty great to see how our has been evolving (or devolving?) over time. There is still some hands-on work needed, to add new contributions and contributors manually, to remove duplicates, etc. So it is not perfectly hands off.

But it could be… Here are some potential features I would have loved to have, or if they exist, I am unaware of:

  • Define Groups for Authors: It would be great to define groups for people. I am sure faculty would love this feature to track their group publications. With this feature, we could have simply created a group and have each project member join the group from their scholar pages (maybe even have a time range, but that is kind of flaky, because of the lag in publication times).
  • Define Project Tags for Papers: It would also be awesome to have tags for papers, so we could match them with projects, groups, etc. With both options, we could have simply created a group+project profile by specifying which group and what tags, and the intersection would autofill.

It does not escape me that this requires some curation, and i could always extend with the same manual steps I did above, but with some incentive I could see this working. I am also sure Google would be smart enough to auto-add/propose tags/groups for us.

Image/Social Impact: My main intentions for this was not to write about science impact and Scholar—that was an obvious, straightforward solution. At least the details above segways to what’s next. This year I was looking into three projects and their image/social impact. Just as above, I had no intentions of making a static spreadsheet. And it seems fairly obvious that I was looking into a something like a Scholar for web content, like blogs, press releases. I was hoping a read-it-later service like Pocket—one of my favorite tools—would take care of business here, or some social bookmarking would work. To my surprise, I cannot seem to find the right tool that fits the purpose here. I ended up using Google Sheets for this and some custom Apps Scripts, based on what I learned from these two folks:

I started with s spreadsheet from the first blog, and changed some queries based on the second one. With a few trials and errors I had a simple solution that looks like this:

Screen Shot 2015-08-11 at 10.46.09 PMYou simply paste a URL and almost everything is autogenerated from there on, except for one thing: The title (Well, in reality when & where as well, but those are not really critical for me). It did not occur to me, but title/excerpt is one piece that is not trivial, based on different contents. Ideally, I think it would be very nice to have something like Pocket’s view, and at some point I might revisit this for such an experiment (enjoy the shameless plug on the selected 1st and 3rd example titles;)):

Screen Shot 2015-08-11 at 10.53.57 PMAbove spreadsheet solved my problem, but is far from effortless, and far from pretty. I am surprized to see i cannot find a good solution that combines social share counting and read it later/social bookmarks. I know great add-ons like Social Share Counter and various web services exist for counting, but none that seems to have above collection, categorization, aggregation features.

I would like to pose this as a feature request for Pocket: Please consider adding social share counts for bookmarks, and aggregations for tags/lists. Please also feel free to set me straight with any existing potential candidates for this.


Selenoid Blog

It turns out I somehow end up working on image management whether at work or at home. At work, VM image management, and at home, JPEG image management… I recently created another blog called Selenoid for the home part here:

SelenoidWelcomePageAs it says on the landing page, the goal was to create a camera roll for our pictures, and it is only fair to call is “Selenoid” since 99% of our pictures feature Selen.  The main motivation was somewhat more than just a place to put our pictures. What instigated this was, a couple of activities with bunch of other friends, and a whole bunch of 10MB emails flying back and forth with group pictures. Instead of emailing each other a bunch of pics, it seemed a good idea to have a single sink point where everyone can send or upload theirs, and can see other pics. All the prettying and gallerying automatically done for you, and you can bulk download all. After playing with a few album tools, I ended with this blog platform.

The requirements were pretty simple at first (later on, it turned out to be more, but we’ll come to that):

  • Simple to upload
  • Easy to download
  • Nice enough to view online
  • Commenting/captioning enabled
  • Private

For simple, since everyone was already emailing things around, it seemed straightforward to just use the same flow using post via email from Jetpack. Easy to download is fairly easy with the media library, the blog format is reasonably easy on the eye, and it is natural to include comments. For private, I used the “Private Only” plugin, which works nicely. Now anything besides the landing page brought up the login page:

SelenoidLoginPosting pictures required no access, as long as you had the special email address, but viewing needed login. It seemed all was good under the hood at this point, and experimentation started. After a few iterations two new requirements became obvious:

  • Categorization
  • Multitenancy

The first one is obvious, and fairly straightforwad. The landing page describes the details of how to push categories during post-via-email. Multitenancy is a tough one and needs explaining. Once you start pulling in posts and categories from multiple events, you want to isolate which tenants see which content. There are a bunch of plugins that provide this and CRM like frameworks. I have used “Role Scoper” which is reasonably fine grain, and works well. It was, however, not fun to deal with setting roles with each individual user and thinking how this scales out. Setting roles, also somehow started to break post via email, so eventually, we ran out of playtime here. It is quite amusing multitenancy gives me grief both at work and at home. Right now, we have roles scoped, but disabled by default. So I defer strong isolation for simplicity. Here is an example Roll from a few pushes via email. Reasonable end result (captured as WYSIWYG via FireShot) i think with minimal effort:

SelenoidPageExThis was a fun experience, and I learned quite a bit from the experimentation. Here is a list of all the packages I ended up using for the final version:

– Akismet
– Confirm User Registration
– Jetpack
– Private Only
– Private Only, Disable Feed
– Role Scoper [Disabled]

We dont use this service much nowadays as shared iCloud Streams make it so easy, but still, not everyone has iOS devices, and there has been quite a few instances where email-to-Selenoid proved to be quite useful. I hope to revisit multitenancy at a later time and update this with a proper service with multi-user isolation.

My First Email Post and What I Learned about Posting via Email

This is my first post via email. Which originally said “Hello, this is my first email post..“. [Published on: Sep 28, 2014 @ 23:02]


Here is what I learned over time:

I am using JetPack’s Post via Email, which needs an actual WordPress account to connect to WordPress and to create a email. Once you generate this secret email, you can post by emailing to that address.
Here is the info:

Next I wanted to add a custom email that I can use, so I used a forwarding service on top. Forwarding service works fine for text updates and small images (~100KB), but fails with bigger images. The secret WordPress email still works with bigger images (3-4MB)

Want to give postie a shot sometime as well:

Will update as I go
