Apple Siri's Architecture

Apple siri has evolved many times and each and every time it has managed to bounce back with solid capabilities, sky is the limit and we can only expect some or other kind of improvement in the architecture as the technology evolves. These guys have not given an inch to rivals.

Apple Siri backend runs thousands of services and they are running on equal number of nodes. Siri’s Application data resides in HDFS (Hadoop distributed file system) cluster . Apple have created a proprietary PaaS-like scheduler framework named J.A.R.V.I.S., which allows developers to deploy Siri services in a scalable and highly available manner.

Apache Mesos is the one that Apple Siri is leveraging for backend cluster management, it serves the CPU, Memory and computing resources abstraction very well, to prove the capability, following is the data published by Apache Mesos

Apache Mesos Features
  • Scalability to 10,000s of nodes
  • Fault-tolerant replicated master and slaves using ZooKeeper
  • Support for Docker containers
  • Native isolation between tasks with Linux Containers
  • Multi-resource scheduling (memory, CPU, disk, and ports)
  • Java, Python and C++ APIs for developing new parallel applications
  • Web UI for viewing cluster state

Incoming corpus, huge text input makes it possible to identify the pattern on the fly and Viterbi algorithm type algorithm can be used .

“If Apple trusts Mesos to underpin Siri — a complex application that handles Apple-only-knows-how-many voice queries per day from hundreds of millions of iPhone and iPad users — that says a lot about how mature Mesos is and how ready it is to make a big impact in companies of all stripes.”
I would love to hear from others to connect the dots and provide their input and understanding.

The Bourne Betrayal | Book Review

Novel by Eric Van Lustbader and Robert Ludlum I like all Robert Ludlum’s novels including those which are written by Evan Lastbadder. To me his novels have taken fiction to the next level. During my way back to Hyderabad from my last summer trip to hometown I bought paperback version of “The Bourne Betryal”. This novel was full of Lastbadder’s style of writing than Robert Ludlum’s one.  I took almost 6 months to complete it. This novel has something different to offer actually. Plot is exciting but the story is not very accelerating. Jason bourn and Martin Lindros, When martin Lindros decided to come back in the field operations with the aim to destroy Fadi and When Martin is out the track , Jason is the only help possible in the situation. Story takes you through various struggle of Jason to bring Martin back home. There are few things where author has not even paid any attention for example how does an ordinary Pakistani Waiter will have that much of information   Towa...

Google and Facebook's Data Center

I think Capacity wise Facebook is the good place to start as no other website has experienced kind of volume and traffic that Facebook has witnessed in the recent past. As you have not specified whether You want to know more about the infrastructure, security or you are interested in their operating model, staff size and remote site management? I would go with the general details. Facebook has multiple data centers around the world and the reason behind this is a common knowledge i.e huge volume of the data that FB process on daily basis. Facebook is currently the world’s most popular web site, with more than 1 trillion page views each month, according to metrics from Google’s DoubleClick service. Facebook currently accounts for about 9 percent of all Internet traffic, slightly more than Google, according to HitWise. This is the first data center of the Facebook in Prineville FB realized that they need many data centers in different locations to support the performance demand of...
