Introduction
Cloud computing has become an integral part of enterprise architectures in recent years. With the rapid advancement of technology, enterprises are now looking to migrate their IT infrastructure to the cloud to take advantage of its numerous benefits. In this blog post, we will discuss the concept of cloud computing for enterprise architectures as proposed by S. Srinivasan and S. Arulkumar in their paper, Cloud Computing for Enterprise Architectures. We will delve into the key components of cloud computing and how it can be implemented in enterprise architectures.

What is Cloud Computing?
Cloud computing can be defined as the delivery of computing resources, including software, storage, and processing power, over the internet. It allows users to access these resources on-demand, without the need for physical infrastructure. Cloud computing enables enterprises to be more agile, efficient, and cost-effective by providing a scalable and flexible IT infrastructure.
Key Components of Cloud Computing for Enterprise Architectures
The key components of cloud computing for enterprise architectures, as proposed by Srinivasan and Arulkumar, are as follows:
1. On-demand self-service: This component enables users to access computing resources on demand, without any human intervention. Users can provision resources such as storage, processing power, and software without any delay, allowing for greater flexibility and scalability.
2. Broad network access: Cloud computing services are accessible over the internet from any location, using a variety of devices including laptops, smartphones, and tablets. This allows for increased accessibility and convenience for enterprise users.
3. Resource pooling: In cloud computing, resources such as storage, processing power, and software are pooled together to serve multiple users. This allows for more efficient utilization of resources and reduces costs for enterprises.
4. Rapid elasticity: The cloud allows for resources to be scaled up or down quickly in response to demand. This feature is especially beneficial for enterprises with fluctuating resource needs, as they only pay for what they use.
5. Measured service: Cloud computing providers use metering systems to track resource usage, enabling enterprises to pay for the resources they consume. This allows for more accurate and transparent cost management.
Implementation of Cloud Computing in Enterprise Architectures
The authors propose a three-layered approach for implementing cloud computing in enterprise architectures.
1. Software as a Service (SaaS): This is the top layer of the cloud architecture and involves the delivery of software applications over the internet. SaaS eliminates the need for enterprises to install and maintain software on their own servers, reducing operational costs and increasing scalability.
2. Platform as a Service (PaaS): The middle layer of the cloud architecture, PaaS provides a platform for developers to build and deploy applications without the need for hardware or operating system management. This speeds up development and deployment processes and reduces costs for enterprises.
3. Infrastructure as a Service (IaaS): The bottom layer of the cloud architecture, IaaS provides virtualized computing resources such as servers, storage, and networking over the internet. This allows for the creation of a virtual data center, providing enterprises with scalable and agile IT infrastructure without the need for physical hardware.
Conclusion
Cloud computing has revolutionized the way enterprises approach their IT infrastructure. By implementing cloud computing, enterprises can benefit from increased flexibility, scalability, and cost-efficiency. Srinivasan and Arulkumar’s concept of cloud computing for enterprise architectures provides a comprehensive approach for implementing cloud computing and reaping its benefits for enterprises. With the continued advancements in cloud technology, it is expected that more enterprises will adopt cloud computing in their architectures to stay ahead in the highly competitive business landscape.
