Several business world digital leaders are investing significantly in all three cloud delivery models (IaaS, PaaS & SaaS). The role and importance of cloud today is undeniable and can be overlooked at ones on perils. Some organizations are leading the change and few have just started their journey.
However it is important to understand public cloud benefits and make an effective case for a public cloud-migration project, which depends heavily on citing the right justifications.
8 Public Cloud Benefits
1. Agility and Scalability
The resource is pay-as-you-go. If an application is designed properly, it is easy to scale in a short period of time. The unlimited scalability and the flexibility to scale up and down very quickly to meet sudden spikes in demand are really unmatched.
2. Cost Optimization and Control
Use functions based on business demand to build and compare the traditional IT cost model and a public cloud cost model. This is still an open conversation as to how much cost is saved. However if deployed properly through the right methodologies, there are substantial cost optimizations to be gained. Build a cost or revenue forecast based on the ability to reduce the cost using new functions or to drive new sources of revenue using new data analytics capabilities.
3. Business Innovation
Cloud enables lower barriers to entry for innovation and prototyping. It is expensive and time consuming to build testing and development infrastructure in-house. The public cloud provider may offer more advanced functional capabilities in the areas of advanced data analysis and processing. Technologies like IoT and AI have opened completely new ways of collecting and analyzing data to deliver real-time intelligent information to customers. With its ability to enable innovation, velocity, and agility, the cloud allows you to create new revenue streams that were previously not possible, letting you quickly move current products and services to the next level today.
4. Broader Geographic Distribution
The global distribution of public cloud infrastructure and platform services (that is, IaaS and PaaS) enables applications to be deployed to other regions quickly and more cost-effectively. Usage of the geographically distributed data centres promises a number of advantages for end users such as opportunity to add additional DC and service availability through redundancy and faster geographical distribution of data.
5. Increased Cloud Application Availability
The major IaaS and PaaS providers have demonstrated high levels of security and reliability. If you have the right application design, you can increase application security and availability accordingly.
6. Shorter Project Delivery Times
Cloud IaaS is a good approach for customers looking forward to experiment trial and error, offering the speed required to test the business model’s success.
7. The Technical Flexibility
As per Gartner, this offloads the responsibility for the configuration and operation of servers, storage, the network and data centers. IT leaders can build the infrastructure-as-code delivery model and modernize applications and services. Security improvement — Use automation to build immutable infrastructure. This approach can improve the infrastructure security fundamentally in terms of automation, templates and elasticity.
8. Improved Security
Public cloud offers extra security layer with strategies preventing and dealing with unexpected downtimes. This saves lot of money for the organizations as it eliminates business disruptions and also protect sensitive data.
