Why monitor and automate your applications in the cloud?

There is no doubt today that Cloud Computing has the potential to bring great benefits to those that adopt it. But, why is it important to monitor and automate things within this area? Well, there are plenty of reasons for you to implement good monitoring and automation tools – most obviously, you can then ensure up-time and availability, reassuring you that your systems are performing well.

With proactive monitoring, you can anticipate any problems before they occur, so instead of waiting to take action until your systems crash, you can identify issues and take proactive preventive actions before these grow into bigger problems or even outages. Scaling your resources based on the workload of your services is one such smart approach to prevent incidents. Automated scaling gives your end-users an improved experience and subsequently increases good customer reputation. Now, imagine if you could automate this process and have your different systems communicating with one another!

Autoscaling in multi-cloud environments

Say that your online service or web site suddenly gets a 10x increase in users. What is your reaction? If you are in marketing or sales, you are likely overjoyed. If you are in operations, and need to keep the service responding smoothly, you might be rather worried. In particular since everybody, including your users and your CEO, will be quite angry if your service fails to respond in a timely fashion (or at all).

Auto-scaling, a primer (for City Cloud’s blog)

Auto-scaling

Servers exist to serve. Either they have actively been requested to work, or they sit idle and wait. Their idle time still costs money, though. A cloud application is said to be over-provisioned if there are too many server instances that sit idle, wasting money. When servers are struggling to keep up with demand that is higher than their combined capacity, the application is under-provisioned.

Auto-scaling is the automated process of identifying when an application is either under- or over-provisioned, and trying to rectify the situation by acquiring or releasing machines. Before the cloud, this was a rather lengthy process, taking hours or days to finish. In a cloud environment, however, resources can be easily and quickly provisioned and auto-scaling is therefore one of the main selling points of the cloud.

Multi-cloud auto-scaling tech demo

In this screencast, Lars, who is a Software Architect here at Elastisys, shows how the Elastisys cloud platform can auto-scale a single application across multiple clouds. This multi-cloud capability allows your application to be easily deployed to multiple cloud providers, or multiple regions or zones within a single cloud provider. Do you have customers that would be best served by servers running in both US East and West? Both EU West and Central? This is the fault-tolerant auto-scaling solution for you!
