There was once a time where any server infrastructure in a business was physical. If you had a domain controller, a print server, an application server, and a file server, chances are your server room had four physical machines laying around that performed these tasks. As time passed and virtualization giants like VMware came into the picture, things changed drastically as there was no longer a need to make all the considerations of commissioning a physical machine whenever you needed a new server. Virtualization provided the ability to buy a single physical server with the intention of dividing its resources among smaller virtual servers.
Now, however, cloud technologies such as Amazon AWS, Google Cloud, and Microsoft Azure are taking shape and many business decision makers are skeptical where moving to the cloud is concerned. Here are a few reasons why making the jump is a good decision.
One of the biggest differences between cloud services and on-premise ones is the pricing scheme. On-premise technologies tend to have a single cost while cloud technologies use a subscription-based model where monthly payments are continuously made. While the cloud alternative is not necessarily cheaper in all cases, this is a deterrent as people consider that the subscription cost will eventually surpass the one-off cost.
This is a misconception as it does not account for the overhead associated with physical servers. They are always on and their power requirements mean that they consume a ton of energy. Also, as years pass their parts fail and replacing them is expensive once the warranty ends. This is no worry with cloud servers as no physical infrastructure is required.
This is where on-premise technology can never stand up to its cloud counterpart. Physical servers have a shelf life. If you purchased a server in 2012 with the Windows Server 2012 R2 operating system, chances are after seven years, your server has seen some wear. You could upgrade it to a Server 2016 operating system but that does not renew the hardware plus it would attract an additional cost.
With subscription-based cloud servers, you receive operating system updates as part of your monthly payment package, and you can make changes to the virtual hardware at any time. Also, because it’s virtual, it technically cannot experience wear and tear.
This is another important part of setting up an IT environment that simply cannot be done as well with physical infrastructure unless large sums are spent. Business continuity and disaster recovery plans are mandatory in the development of IT strategies. With physical infrastructure, redundancy is done in the form of backups to one or a couple physical servers that must be bought.
Cloud servers run on infrastructure that resides in the datacenters of the provider (Amazon, Microsoft, etc.). These datacenters have multiple servers and the providers have multiple datacenters across the world. This allows for both local and international redundancy. Therefore, in the unlikely event that a datacenter is destroyed, your data and environment is unaffected without the requirement of a big spend or the setup of backup servers.
IT personnel doesn’t always expect everything to run smoothly . However, it is usually a much better experience when the discovery that something is amiss happens as a result of a monitoring tool as opposed to user reports. Monitoring and logging are staples in the IT world and can be the difference between a seamless user experience and severe downtime.
The idea of technology is to evolve the way humans work and live, so life becomes easier. Cloud infrastructure feeds into this theory and above you can see the reasons why you need to give it a shot instead of “sticking to the devil you know.”
