Everyone talks about cloud as if they are doing everything on cloud right now and many would claim themselves to be experts of cloud computing to an extent. However, as rosy as the picture may seem, companies are moving their businesses to public clouds without knowing much about the impact, the future or the immediate result. While it may seem absurd that some of the biggest names in IT enterprise are not so sure what they are doing with cloud, it is exactly the issue.
Risk management is a major issue whenever you are moving to a new platform or doing something completely new. Each company, however big or small, runs their businesses on a series of business applications which need to be in top notch condition for a smooth run of business. However, surprisingly, there is hardly any risk management in cloud as companies deploy applications.
What they know and what they don’t
Companies, for a start, do know about the basic practices required on cloud. They do distribute their applications across various data centers but within the availability zone of the centralized server in concern. Hence, if there is a failure in one facility, the application remains unperturbed as long as the others function.
However, big companies have huge data centers which in turn rely on thousands of servers that may lead to hardware failure all of a sudden. So, if you are putting a critical application on cloud unknowingly, it may get damaged and in turn, put the business flow to a standstill. Hence, the first process is to identify such critical applications and then ensure a layer of protection around them to stop them from easy malfunctioning.
If you are dealing with machines, failure is inevitable to an extent. So, rather than wondering about a foolproof system, it is better to learn to combat failures as quickly as possible. So, experts suggest a detailed analysis of the various failure modes and then chart out a recovery method for each and every failure. These actions should be developed in such a way that the recovery can be in the fastest possible manner.
This process has to be carried out with each process by extrapolating with its components and charting out recovery method for each possible problem. You also need to categorize such failures according to their potential and possible frequency. That also gives a clear view of the probability of failures. In short, professionals have to ensure that a small glitch does not aggravate into a large fiasco.
Possible measures and an amount of prescience
If your application has a snag suddenly, then often it shuts down without any prior warning. As a preventive measure, there has to be a retry logic inserted in it such that it reboots itself once before the help desk is called. It is specifically required in case of cloud because IT professionals don’t manage it all in cloud.
Professionals blame it on companies to an extent as they believe most companies consider cloud to be a perfect system without any chances of failure. It is hardly the case and such an assumption only leads to failures. The big companies should be more careful while moving to cloud because they have a larger horde of applications to manage. Ensuring that there is no single point of failure becomes essential.
