The Data Center has always been an integral part of enterprise IT infrastructure. In the past, the majority of companies would have their in-house servers that would run everything from databases to storage locations on their network. While this is still quite common nowadays, many new companies have begun migrating these services over to the public cloud, working with companies like Amazon, Google, and Microsoft.
Gartner, predicts that around 80% of companies will have migrated from a private to the public cloud by 2025. Some have said that this signals the death of the in-house data center, with the focus shifting to public cloud platforms like AWS, Google Cloud, and Azure.
Why are Companies Migrating to the Public Cloud?
The increased level of migration from the private cloud to the public cloud has been fuelled by a variety of increasing needs in the enterprise.
A Reduction in Cost –
One of the biggest reasons for companies to migrate to the public cloud is the cost of maintaining and upgrading server hardware over time.
Amazon, Google, and Microsoft all undertake the maintenance and upgrading of their server clusters, negating the need for private businesses to do so. IT infrastructure also requires significant office space, which businesses can put to better use without on-premises servers.
The tiered packages that cloud providers offer help to reduce costs further by allowing companies to only purchase the computing power that they need. This is fuelled by developments in artificial intelligence, which cloud providers have implemented into their products to provide in-depth analytics and reduce overspend on cloud services.
The next aspect is incredibly beneficial for fast-growing companies. The scalability of your IT infrastructure is incredibly important as it allows your storage and computational capacity to grow with your business. This is something that can be forgotten when planning on-premises installations, resulting in extra space needing to be made and hardware being replaced before it gives a return on investment to the business.
Thanks to the public clouds virtually infinite scalability, many companies have chosen to place their resource heavy applications in the cloud. When storage space begins to run low, artificial intelligence can inform and suggest new packages for businesses to ensure they do not overspend on their IT infrastructure, while always having enough capacity to run their services.
Improve Mobility and Flexibility –
Arguably, one of the most significant benefits of moving to the public cloud is the increase to mobility and flexibility it offers.
Public cloud services are easily accessible on any device, from any location. This makes it easier than ever for employees to work from remote locations without losing productivity or access to job-critical stored data. Businesses have been increasingly moving towards making remote working the norm, as details in this survey by Owl Labs. This has benefits for both employers and employees. Businesses need to purchase less office space when workers are remote, resulting in significant cost reductions. Employees are also reported to be more productive when working at home, and no longer need to undertake the daily commute to complete their work.
Overall, the public cloud is nearly identical in performance for most use cases, as long as a high-speed internet connection is available.
Reasons to Stay On-Premise
The public cloud is increasingly viable to use for business services, ranging from virtual desktop provision to simple cloud file access. There are, however, a few use cases which require lower latency or better security, which can only be accomplished on-premises.
Businesses that are reliant of high levels of security for their business model may find that the private cloud is more suitable for their needs. The public cloud has been hit by a variety of security blunders, meaning security-conscious enterprises may wish to retain their in-house IT infrastructure.
It is entirely possible to run necessary virtual desktop infrastructures in the public cloud. However, niche software packages and better control over operating systems can be achieved when running on-premises. There is also much lower latency with on-premises server infrastructure, which is better when using virtual desktop services.
