The last few years have seen an increasing trend of organizations moving the majority of their data and applications away from public to private cloud environments. The two main reasons for this shift are cost benefits and security advantage as well as other factors such as the proliferation of SaaS and IaaS offerings. In fact, it’s not uncommon anymore for businesses to manage multiple clouds, with several enterprises using as many as up to eight clouds including public, private and hybrid models. The decision of if and when to migrate to private cloud is more a business rather than a technology decision and is unique to each organization.
Several factors affect this decision, be it the need to increase the capacity of your data center or to upgrade critical software or to replace server hardware that is nearing the end of its lifecycle. Whatever the case maybe, migration from public cloud to a private cloud environment is a decision that requires careful planning and implementation so as to ensure seamless transition, minimal hindrance in operations, and the ability to keep pace with evolving technologies and regulations.
As each cloud model has its own pros and cons, the ultimate decision of whether an enterprise should migrate to cloud at all, and if so, which one, should be made after careful consideration.
Whereas public cloud suffers from the disadvantages such as higher security risks, unreliable network performance and lack of customization, private cloud overcomes these cons while also providing some other benefits that many enterprises value. The key reasons why businesses are increasingly migrating from public to private clouds include:
Private cloud offers predictable and optimal performance for your workloads since the network resources aren’t being shared by others. This leads to better control over your resources and the ability to customize storage and computing components as required.
While security and compliance issues don’t completely disappear in a private cloud environment, it still provides a much better ability for enterprises to protect their environment. In addition to better overall security, private clouds also enable businesses to customize their cloud environment to meet their unique security and regulatory requirements.
When it comes to cost-effectiveness, private cloud has a big up over public cloud. A private cloud platform saves time (and in turn, money) through faster deployments which lead to faster time to market. Additionally, it helps avoid vendor lock-ins and heavy upfront investment in technologies that might not evolve in the future as required. Private cloud is especially beneficial for software companies that need high flexibility and customization to establish a continuous CI/CD software development cycle.
