In a broad term, cloud computing is referred to as a collection of different services and cost-effective business solutions that are tenfold the functionality and capabilities of an IT department.
Based on the unique requirements, a venture can choose how, when, and where to use cloud computing to ensure a seamless working environment within the organization. Before we shed some light on the different cloud computing models, let’s explore more about cloud computing.
Cloud computing provides developers with the ability to focus on procurement, capacity management, maintenance, and much more. As cloud computing has gained extreme popularity, multiple models and deployment strategies have emerged as an integral part of maintaining the IT infrastructure. Each segment, including deployment methods or cloud services, offers flexibility, control, and seamless management at all stages.
As per NIST (the National Institute of Standards and Technology), cloud computing is an ideal model that enables on-demand network access to verified configurable computing resources like – application servers. Networks, storage, and so on. This makes automation the most highlighting leverage of cloud computing.
When an organization uses cloud computing appropriately, it helps you remove the layers of management effectively. With this, you will no longer be responsible for the operational systems, physical data centers, hardware, etc.
Three cloud computing service models are
LaaS (Infrastructure as a Service)
LaaS is a self-service model structure that manages the remote data centers and their infrastructures. Infrastructure as a Service offers access to virtual computing machines and other resources over the internet. These resources are hosted by a third-party platform, including – Microsoft Azure, Google, or Amazon Web Services. The current trend in the IT sector is purchasing LaaS based on the consumption model. This process is more like buying electricity. Here, you pay for what you utilize. Most organizations prefer LaaS because of its easy reliability and better access to the virtual environment while keeping the regulatory prerequisites in mind.
SaaS (Software as a Service)
SaaS has replaced the old-school on-device software operational processes with its intuitive software, which requires a subscription. With this, it has become an integral part of most outsourced IT support service packages. It can be accessed through almost any web browser without any installation or downloads. This is a licensed software centrally hosted right in the middle of the cloud. An ideal example of Software as a Service is Salesforce.com.
PaaS (Platform as a Service)
PaaS permits an organization to develop, run and manage a different set of applications without the need for an IT infrastructure. This helps to fasten up the deployed applications. With this, the developers can better focus on writing codes and developing applications without worrying about the IT infrastructure activities consuming their maximum time.
The last word
Unarguably, a successful move to cloud computing is not all about PaaS vs. SaaS vs. LaaS. Instead, it’s a well-planned trick that enables a long mitigation roadmap to better IT planning and maintenance. Here, all you need is to understand the literal functioning of all cloud computing models before implementing them in your business operations.
