Cloud computing has profoundly transformed businesses. According to a 2021 survey by Forbes, 43% of IT leaders say that platform and service flexibility is the top benefit of multi-cloud platforms. The study suggests that 81% of enterprises have at least one application or segment of their infrastructure in the cloud today. The 2020 Data Attack Surface Report indicates that by 2025, there will be over 100 zettabytes of data stored in the cloud IT infrastructure.
The public cloud, private cloud, and hybrid cloud are the three main types of cloud computing deployments. There is no one size that fits all. The type of cloud to be deployed depends on the business requirements.
The public cloud is the most common one, and it’s owned and operated by third-party service providers. With a public cloud, all hardware, software, and other supporting infrastructure are owned and managed by the cloud provider. An example of a public cloud is Microsoft Azure. In a public cloud, you share the same hardware, storage, and network devices with other organizations, or “tenants.”
Public cloud deployments are frequently used to provide web-based email, online office applications, storage, and testing and development environments. Lower costs, and unlimited scalability are some of the advantages of using the public cloud. The biggest disadvantage of a public cloud is the fact that the security of data held within a public cloud is a cause for concern. Another issue is that of performance. An increase in data usage across the internet may affect the speed of data transmission.
A private cloud, as the name suggests, is used by just one organization. Consequently, the cloud infrastructure of a private cloud (the physical servers that host the private cloud) is maintained by that organization.
The hardware and software are dedicated solely to the organisation. These are mostly used by government agencies and large organizations. Privacy, better control, and flexibility are some of the advantages of a private cloud. On the downside, private cloud services come with a higher initial outlay. But this balances out in the long term.
A hybrid cloud combines the advantages of public and private clouds. The biggest advantage of hybrid clouds is that they allow data and apps to move between the two environments. With a hybrid cloud solution, you can, for example, use public cloud resources only when required, saving you a lot of money in the meantime.
Several organisations are choosing the hybrid cloud approach increasingly due to advantages such as addressing low latency issues and meeting regulatory and data sovereignty requirements.
The cost associated with the maintenance and installation of the hybrid cloud infrastructure is high. The chance of misuse of the hybrid cloud infrastructure contracted by third-party vendors can’t be neglected either. Organizations like Skillmine Technology Consulting offer cloud infrastructure services covering all aspects of cloud deployment and support. Skillmine’s services include cloud operations, migration, solutions, and optimization.
According to Market Research Report 2021 by MarketsandMarkets, the total worth of the cloud infrastructure services market was $371.4 billion in 2020. This is expected to reach $832.1 billion by 2025, with a compound annual growth rate (CAGR) of 17.5%, indicating that non-cloud data centers are on their way out and will be replaced by cloud data centers in the near future
