HIPAA compliant cloud infrastructure on AWS – Case Study

Category: Case Studiesmurali @ 10:56 am

In August 2010, hCentive, selected  Dinoct to architect, setup & manage secure and scalable health insurance portal.  Within two months, Dinoct successfully implemented a secure, scalable & HIPAA compliant infrastructure on Amazon Web Services (AWS) platform.

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.

A case study of the implementation is available here  hCentive Case Study

Dinoct graduated from NVTC’s Fall 2010 FastTrac® TechVenture™ program

Category: Newsmurali @ 1:35 pm

I represented Dinoct in NVTC Entrepreneur Center’s Fall 2010 FastTrac® TechVenture™ entrepreneur training program. 11 companies from DC metro area participated and graduated from this program. NVTC organised graduation ceremony on December 7th, 2010.

http://www.nvtc.org/press/enews/atnvtc121410.php?utm_source=eNewsletter121410FastTrack1Link&utm_medium=email&utm_campaign=eNewsletter121410&#fasttrack

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.

Nginx – Small, But Very Powerful and Efficient Web Server

Category: Web Serverbilal @ 2:19 am

Nginx is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server. Igor Sysoev started development of Nginx in 2002, with the first public release in 2004. Nginx now hosts nearly 6% (13M) of all domains worldwide.

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

Given below is a list of top Web server software vendors published in a Netcraft survey in January 2010.

Vendor Product Web Sites Hosted (millions) Percent
Apache Apache 111 54%
Microsoft IIS 50 24%
Igor Sysoev nginx 16 8%
Google GWS 15 7%
lighttpd lighttpd 1 0%

Data Migration Case Study

Category: Case Studiesvineeth @ 1:07 pm

Our client Innovectra has many 3-Tier web applications which were hosted on multiple server’s. As part of addressing customer demands and to meet volume projections client was actually planning to enhance and realign the current infrastructure capability. This involves migrating production applications to higher computing platforms.

Although our client tried an initial attempt to migrate data, they were not able to handle some of the complex tasks involved in legacy application migration. OPSMetrics was asked to demonstrate our capabilities and were finally selected for our experience and capabilities.
