Invasion of Cloud Computing
We all are very well aware of Cloud computing, they way it works and the way it has made things convenient. Practically, cloud computing is ready to invade the technology sectors. If we believe the stats presented by experts, we may see quadruple increase in traffic in next few years. In coming few years, almost 90% of workload will be take up by cloud data centers in comparison to conventional data centers.
Internet of things and Big Data can be considered as prime reasons for such a big invasion of cloud computing.
By 2020, database, analytics and IoT workloads will account for 22% of total business workloads, compared to 20% in 2015. (Source : forbes.com)
Virtual layers used in cloud computing gives a huge flexibility. Architects don’t have to waste their time of chopping off the size of servers. It is very easy to tear down and spin the servers. Capacity of servers can be expanded very easily, be it CPU, disk space or RAM. It allows the architects to decrease the rack space and power usage very efficiently.
From small scale enterprises to big companies like ‘Alibaba’, everyone is giving much attention to their cloud computing unit. Virtualization helps in increasing the security of application and helps a lot in saving time and it is much hassle free.
The biggest advantage of Cloud computing is Disaster Management and Recovery. You can achieve a great redundancy when you connect a SAN to private cloud. Another benefit of cloud computing is automatically shifting of server resources. But for this you need an N+1 environment, which mean you need one extra server for switching to it in case of downtime or disaster. When configured correctly you could power off one server and it would automatically shift the virtual servers over to an available server in your cloud. Taking your disaster protection up one level, you could have another SAN in another data center and perform SAN to SAN replication for a hot site DR environment capable of full recovery in less than 1 hour.
By 2020, consumer cloud storage traffic per user will be 1.7 GB per month, compared to 513 MB per month in 2015. By 2020, video streaming workloads will account for 34% of total consumer workloads, compared to 29% in 2015. Social networking workloads will account for 24% of total consumer workloads, up from 20 percent in 2015.
These stats clearly shows that on consumer side, users also prefers to use cloud storage. The reasons are quite simple, cloud storage is fast, convenient, flexible and safe than conventional storage platforms. This rising inclination towards cloud computing may result a steep fall in IaaS (Infrastructure as a service). But on the other hand it would open opportunities for other services like SaaS (Software as a Service) and Paas (Platform as a Service)
