One of the major requirements of HIPAA being the ability to ensure secure handling of sensitive customer healthcare data, our greatest challenge was the need to supplement AWS with 3rd party solutions to deliver a fully compliant infrastructure.

As a participant, and from my perspective, this 10 week program was very informative & useful. It gave opportunity to listen to the stories of successful entrepreneurs, guidance & advice from experienced coaches and more importantly establish relationship with the entrepreneur community (participants, coaches & guest speakers) from the area. I did enjoy the program.

Summary notes:

* First of all the program was very well organized. Kudos to Kristin D’Amore for the excellent organization of the program
* Well rounded selection of guest speakers (except one out of ten)
* Excellent venue.
* Training materials & resources are very useful and well prepared.
* One of the key take aways from these sessions was about the importance of “communication skills” (story telling) for entrepreneurs. It would have been great to have a session on communication skills.
* Most of the participants were found to be at concept stages but the sessions seemed to have spend more on funding stage details.

I’d highly recommend this program to those who are venturing into entrepreneurship.

This was a challenging and interesting project that involved various cloud and open source technologies. Some of the highlights of this implementation are :

* HTTPS enabled load-balanced server clusters
* SSL enabled server component transactions
* SSL enabled database replication
* Encrypted disk volumes & storage components
* Security hardened server & database components
* Redundant multi-availability zone based components
* 24×7 monitoring and service desk

* providing managed services to ensure higher uptime, availability and performance of those business-critical systems
* administering and managing production, staging environments and infrastructure entities
* deploying application and 3rd party software components
* providing 24×7 service desk to manage customer support issues
* managing and testing DR plans

Nginx is known for its high performance, stability, rich feature set, simple configuration, and low resource consumption.

Nginx is one of a handful of servers written to address the C10K problem. Unlike traditional servers, Nginx doesn’t rely on threads to handle requests. Instead it uses a much more scalable event-driven (asynchronous) architecture. This architecture uses small, but most importantly, predictable amounts of memory under load.
Even if you don’t expect to handle thousands of simultaneous requests, you can still benefit from Nginx’s high-performance and small memory footprint. Nginx scales in all directions: from the smallest VPS all the way up to clusters of servers.

Nginx powers several high-visibility sites, such as WordPress, Hulu, Github, Ohloh, SourceForge and TorrentReactor.

Main features of nginx server:

* Handling requests to static content, automatical handling of index files and building directory listings.
* Accelerated proxying without caching, simple load banancing and fail-over.
* Accelerated support of remote FastCGI servers with simple load banancing and fail-over.
* Modules and filters including compression (gzip), byte-ranges, chunked responses, SSI-filter, concurrently executed FastCGI or proxy subrequests from one SSI-page.
* SSL-support.

Advanced features of nginx server:

* IP-based and name-based virtual servers.
* Support for keep-alive and pipelined connections.
* Flexible configurations like in Apache, tunable timeouts and buffers.
* Config file and even executable file updating without any termination in service.
* Tunable log files with fast rotation.
* Special pages for errors 400-599.
* Very efficient URI rewriting with regular expressions.
* Access rules based on client’s IP address and on pasword (Basic auth).
* Download speed limits.

Main architecture specifics of nginx server:

* One management and many worker processes; workers are running from non-privileged user.
* Support for different techniques for asynchronous sockets handling: kqueue (FreeBSD 4.1+), epoll (Linux 2.6+), rt signals (Linux 2.2.19+), /dev/poll (Solaris 7 11/99+), select and poll.
* sendfile() system call support: sendfile (FreeBSD 3.1+), sendfile (Linux 2.2+), sendfile64 (Linux 2.4.21+) and sendfilev (Solaris 8 7/01+).
* Accept-filters support on FreeBSD 4.1+ and TCP_DEFER_ACCEPT on Linux 2.4+.
* Very efficient memory handling: it needs only 2.5Mbytes of RAM for 10000 inactive keep-alive connections.
* Minimum of memory copying operations
