While you may be embracing the cloud, moving mission-critical applications to the cloud may be a sticking point. In a recent survey looking into top concerns for deploying apps on IaaS clouds, reliability ranked highest with 90% of respondents rating it somewhat or extremely important. Moving to the cloud means that you rely on the cloud providers’ underlying services. Are those underlying services, such as application delivery controllers, ready for prime time?
Most public clouds provide usage-based pricing and associated cost savings, but provisioning, scalability, availability, reliability, security, and disaster recovery issues create potential obstacles to adoption, especially for the “bet your business” applications customers would like to run in the cloud.
Until now, when you want fault tolerance for your load balancers on EC2, the only option you have is an active-passive cluster, which doesn’t offer real fault tolerance. Amazon ELB offers horizontal scaling but does not offer the advanced ADC features found in Stingray Traffic Manager software.
Another disadvantage for active-passive is that one load balancer sits idle until it’s needed and you pay for services that you’re not actively using. To get over these hurdles, we just announced new features that will allow you to reliably scale your ADC and put mission-critical applications into Amazon EC2.
We’re the first vendor on Amazon EC2 to offer active-active ADC services for large fault-tolerant clusters. Active-active means hosting multiple Traffic IPs on multiple Stingray Traffic Manager instances with Traffic IPs distributed across Stingray Traffic Manager nodes in a cluster. This means that a Stingray Traffic Manager cluster collectively handles traffic to all applications. When deployed as a cluster into a VPC, it can actively process traffic, saving you money and offering the highest level of reliability and horizontal scalability. In addition, you can install Stingray Traffic Manager as software onto a Linux instance of your choice allowing you to add custom software and configuration to avoid the constraints of using an AMI image.
Mission-critical applications will also require advanced features that only a mature, agile ADC like Stingray can provide today, such as:
