Data from Research and Markets shows that the cloud computing marketing which stood at $272 billion in 2018, will grow to $623 billion by 2023, at a CAGR of 18% Y-o-Y. Moreover, with the massive exodus to the cloud, 80% of companies are predicted to close their traditional data centers by 2025, according to Gartner Research.
This is clearly an indication that Cloud computing is the trend that’s here to stay. Cloud has an indomitable potential that offers business exactly what it wants and the onus only depends on the business owners as to how they unwrap it and turn it to their advantage. And now the question is- How can you judge what’s best for your organization. There are many cloud computing models, platforms and there are different ways your data resides in your system. Moreover, there are different futuristic use cases you would want to deploy in your organization. How do you decide what’s the best cloud computing approach for your business? Read on to understand.
The different avatars of Cloud Computing
The cloud has something to offer to everybody in the organization – it can serve the IT specialist in the company by providing networking and infrastructure services with IaaS or Infrastructure as a Service. It can offer a sandbox for software development and testing for programmers with Platform as a Service or PaaS. It can even offer ready-to-use software applications that are directly used by end users via Software as a Service or SaaS. Each of these cloud computing service models offer users varying degrees of control, customization options and security. Where and how to use cloud depends entirely on what you want out of cloud.
Another aspect is to check where and which type of service your data and systems will live in. You’ll have to choose between different cloud delivery models, to set your path forward.
The Cloud Models- Pros, Cons and Use-Cases
The difference between the 3 cloud deployment models was once easily defined by location and ownership. But it’s not simple anymore. There are a lot of weighing factors. So while we compare the differences below, there are many caveats.
A public cloud is a multi-tenant cloud environment created from IT infrastructure and are not owned by the end-users. In this type of cloud model, all the resources are shared by the end users and subscribers unlike private cloud where the resources are owned by the organization themselves. The service can be charged free, freemium or subscription based on the computing capacity consumed.
Here the cloud vendor is responsible for handling the development, management and maintain of the computing resources shared between multiple tenants across the network.
When to use the Public Cloud:
The Public cloud is used:
- In situations when the amount of the computing capacity and users you require.
- When You need cloud based apps and services to perform IT and business operations
- When you need additional resource requirements to address varying peak demands
- When you need software and Test Environments to be worked upon.
Advantages of Public Cloud:
- The hybrid clouds have a highly flexible environment that can be scaled up and down according to the fluctuating demands.
- The cloud vendor is responsible for maintaining the infrastructure and as a result there’s decreased complexity.
- Cost savings is achieved as there isn’t separate investment required to deploy and maintain the IT infrastructure and flexible pricing options.
Limitations of Public Cloud:
- As the control lies in the hands of the cloud vendor, there is less visibility of what’s happening to your mission-critical applications. However, this can be fixed by establishing a clear communication between your IT staff and a Managed Service Provider.
- The lack of visibility and control also takes a backseat on the compliance and governance aspects of your organization.
- Total Cost of ownership can raise in case of mid-sized to large organizations, which however, must be optimized as the part of the process.
When you want the best of both worlds- you can choose the hybrid Cloud. The resources are integrated into an environment where the apps
and data workloads and resources are shared between public and private cloud deployment based on organizational business and technical policies around security, performance, scalability, cost,and efficiency, among other aspects.
If you want to use private cloud environments for IT workloads but implement public cloud resources, that’s best used to accommodate the spikes in the network traffic. This hybrid approach helps to deliver the costs as a part of short-term IT costs associated to public cloud instead of the Capex costs associated with private cloud.
When to use Hybrid Cloud
- A hybrid cloud can be used when your workloads demand cyclical resources and you do not want to add permanent resources.
- When your organizations demand different levels of customizations on various verticals of security, regulatory and performance requirements
- When you want to optimize your cloud environments to the maximum without having to compromise on whether it’s a private or public cloud.
Advantages of Hybrid Cloud
- Hybrid cloud gives a good stage to develop and test use cases in the public cloud. Later you can understand the cost curves and modify production workloads accordingly.
- It reduces your overall Total Cost of Ownership as it helps run steady workloads and allows you to transition into an OpEX model.
- Hybrid cloud can be used to configure private cloud to match the legacy performance requirements that only dedicated servers can offer, while spinning up additional resources On Demand
Limitations Of Hybrid Cloud
- As you are running two-levels of cloud infrastructure simultaneously, there can be compatibility issues especially when apps and data reside in different environments.
- Organizations that deploy large data files on public clouds may suffer latency issues, while bandwidth usage could create bottleneck issues for other apps.
- Security can be challenging owing to data-sharing, regulatory compliance in the aspects of both public and private cloud.
