The solution

Virtusa designed and developed the agency's primary public web portal, and integrated the most popular social media and social networking sites into the portal.

This portal involved a cached content delivery network, interventions in operations of two enterprise-scale data centers, implementation of an agency-wide CMS, and full integration of the agency's public content. Virtusa built the platform to meet the client's SLA requirements like support for 25,000 TPS (Transactions per Second) at the origin servers - The site will utilize a CDN; traffic at the CDN typically is 150,000 TPS for large events. 25,000 TPS flows through to the origin servers.

Other requirements included:

700K+ web content (pages/files in repository)
Varying page sizes - For instance, the client's home page is 250 KB (Text/HTML), post-Gzip compression it is ~34 KB, associated content for the client's home page is an additional 2900 KB
15 Gbps of bandwidth on the CDN end with 3 Gbps flowing to the origin

Availability requirements:

99.995% SLA including any planned or unplanned downtime
100 % SLA during missions which could be a 36-hour timeframe
Availability of content globally within 7 minutes of publication

Working with limited metadata, Virtusa designed an intranet portal and a single CMS repository for more than three million assets including 500,000 webpages. For the intranet portal, Virtusa used open source platforms like Liferay and Alfresco, and commercial products such as Google Search Appliance to improve search relevance.

The portal merged more than 10 enterprise applications for content management, forums, knowledge management, and databases. Virtusa migrated thousands of resources to the new portal, using an agency-wide taxonomy to classify assets.

Virtusa also created an enterprise-wide community portal, Spacebook, which is based on Liferay portal technology. Content from the client's existing intranet portal and communities were migrated to Spacebook. For robust and secure access to the agency's applications, Virtusa implemented a security platform with centralized authentication, including secure multi-level authentication, for diverse application types.

Virtusa planned, managed, executed, and monitored infrastructure activities for the Agency Modernization Program. The team delivered value-added, innovative enterprise technology solutions, including hardware, software, shared applications and data, and security, that was integrated into the agency's modernized infrastructure.
