How Reliable Is Cloud Computing?

Cloud computing may be the new system which had guaranteed a lot of things within the structure and conduct of economic to online organizations and companies. These new, enhanced processes include better versatility, reduced costs, greater performance, advanced security, managing ease, and reduced infrastructure investments amongst others.

Reliability, however, may be the best concern among IT managers when mentioning to the 550d set by cloud computing systems. (Typically, 3.65 times of down time each year is average for non-redundant hardware, such as the reload duration of the operating-system and backup restorations.)


For that organization, downtimes are usually considered as planned or unplanned. Cloud computing has some benefits for planned downtimes. However, it may make the greatest impact on companies in lessening unplanned downtimes.

Planned downtimes are often from the section of vendors of cloud computing unless of course they provide IT operation services too. These planned downtimes are often software maintenance, upgrades, or scheduled equipment repairs.

Unplanned downtimes

In cloud computing, planned downtimes are stored low because that belongs to what they’re selling (supplying high uptime). Unplanned downtimes are in which the cloud vendors can provide probably the most, or where they are able to lose probably the most.

They’ve the knowledge and proven processes that may produce overall network (and hardware) reliability that may exceed individuals of average data centers, or colocated or solo servers.

Service level contracts (SLA)

Regardless of the claims of reliability, merely a couple of cloud vendors have fixed SLAs that may assure controlled down time or present reimbursements for added down time. Vendors with appropriate software with self-healing qualities offers better guarantees within their SLA using their clients.

Some big organizations don’t normally guarantee this degree of services. Individuals cloud vendors with self-healing software (or some similar technologies) can continue to suffer unplanned down time for a lot of reasons, foremost being human error.

Backup copies

To make sure an airtight reliability, a great backup strategy is essential. However, in cloud systems outfitted using the latest highly reliable software technologies, managers have a tendency to forego such necessary backup copies.

Without backup copies, systems which are lower is going to be lower for any lengthy time, which is applicable to cloud or non-cloud systems. Loss of data is another very probable prospect. The only real saving elegance that cloud computing systems have within the others may be the affordable and enormous storage facility to keep the backup copies.


For many, another security measure used is copying their data in one cloud vendor to a different. However, a lot of today’s backup software are equipped for physical servers and never the virtual conditions inside a cloud computing company.

The finish outcome is these solutions might entail expense. A lot of today’s backup programs usually charges on the per server basis.


Another reliability component that usually escapes most customers, especially individuals new to everything about cloud computing, is monitoring. Unplanned downtimes could be disastrous for your system and also to your computer data.

An online monitoring system can scan you servers regularly for problems, impending application problems, or perhaps present performance levels. These may warn you of impending down time or problems that induce downtimes.

Good reliability inside a system, whether in cloud computing or else, still needs traditional traditional approaches in fixing problems.
