How resilient is your cloud platform?

One of the many benefits of cloud computing is anytime, anyplace access. Cloud in general boasts high availability, but have you looked at the resiliency specifics of your cloud platform? Is it single-site or dual-site? Where does it fail over too - if anywhere? Does the platform replicate? Is it active-active? These are all questions that you should know the answers to if you are to properly understand how resilient your cloud platform is.

Most cloud platforms run from a single site. One site, in one location. The problem with this is that if the site goes down, you lose access to your digital data and applications. If you want to achieve that all important 100% uptime guarantee then considerable time, effort and cost would be required to configure two separate cloud platforms to create dual-site cloud. This provides effective disaster recovery for your business-critical data and applications because if the first site fails, you can perform some network reconfiguration and continue using the second platform. This means business continuity in the event of an outage at the site of your first cloud platform. 

Taking things one step further, to achieve an even higher level of resilience you could look at an active-active cloud infrastructure. This is essentially two cloud platforms linked together, and running simultaneously, similar to the dual-site example as outlined above. If you can find a provider that offers active-active cloud as standard, then the considerable time, effort and cost that you would have spent building two sites is eliminated as all that work is done for you.

The big benefit of active-active cloud is that any data that is saved to, modified, or updated on the primary platform, is automatically replicated to a secondary platform. This gives you two identical platforms, in different, geographically separate locations, which run identically to provide two synchronised hosting environments. So it’s different to a cloud backup, as the two sites run and update in tandem. 

This means that should the primary site fail, or experience downtime, the secondary site continues to function and serve the data so that you can continue with business as usual. The failover to the second site is automatic, so you don’t even experience a minute, nor a second of downtime.

Teledata’s cloud platform - CloudActiv - provides just this. CloudActiv is active-active as standard, built using VMware vSAN stretched cluster technology to provide constant, sub-millisecond replication between two identical platforms, in two separate UK locations. The automatic failover gives an RTO/RPO of near zero providing built-in disaster recovery as standard.
