Due to its ever increasing customers and connections Wyless required more scalability and efficiency but definitely at a cheaper cost. Usage records & calculations for more than 2 million connections does not reside in gigabyte of space, it requires terabytes of space. Where connectivity is the key to your success or failure in business, you don’t want your machines to be responsible for slow response. Wyless had all of its servers managed at another hosting. Ex-Hosting became non-scalable to support the ever-expanding needs of expansion Wyless required. But moving instance from Ex-hosting was the biggest challenge. Wyless had issues of stability, network availability, scalability & OS. Resulting in not able to scale up the resources like Disk, CPU and Ram without incurring downtime.

At Atlassian, growth is on a fast track. The company adds more customers every day and consequently needed an easy way to scale JIRA, which is growing by 15,000 support tickets every month. The instance supporting this site was previously hosted in a data center, which created challenges for scaling. “The scale at which we were growing made it difficult to quickly add nodes to the application,” says Brad Bressler, technical account manager for Atlassian. “This is our customer-facing instance, which gathers all the support tickets for our products globally. It’s one of the largest JIRA instances in the world, and growing and maintaining it on premises was getting harder to do.” For example, the support.atlassian.com instance was hosted on a single on-premises server, which the company needed to frequently take down for maintenance.The company also needed to ensure high availability for JIRA. “This is a mission-critical application, and the number of customers potentially impacted by downtime is huge,” says Neal Riley, principal solutions engineer for Atlassian. “As we grew, we became more concerned about the resiliency and disaster-recovery capabilities of the data center.”To move into a more scalable, highly available environment, Atlassian created JIRA Data Center, a new enterprise version of the application. However, JIRA Data Center required shared storage. “We needed a shared file system so the individual application nodes could have a shared source of truth for profile information, plug-ins, and attachments,” says Riley. 

Vodafone found that traffic for the applications peak during the four-month period when the international cricket season is at its height in Australia. During the 2011/2012 cricket season, 700,000 consumers downloaded the Cricket Live Australia application. Vodafone needed to be able to meet customer demand, but didn’t want to invest in additional resources that would be underutilized during cricket’s off-season.
