Cloud adoption has become a critical part of most enterprises’ IT plans, so it is crucial to pick the right type of your business. Cloud computing comes with lots of benefits such as cost savings, a decrease in excess capacity, and standardization on a shared database and application platform. Cloud computing is known for its speed and agility, and it also allows enables new services to be deployed much faster. If you are confused about which type of cloud solution is right for you? Then read this article to know about the three primary cloud deployment and service delivery models.
Different Cloud & Service Options
The main value of the cloud lies in the services delivered, and there are basically three main service types ) in cloud computing, namely SaaS (Software as a Service), PaaS (Platform as a Service) and IaaS (Infrastructure as a Service
The most common and well-known type of cloud computing is a pubic cloud in which a service provider basically supplies services such as applications, platform and infrastructure to your organization over the Internet. If your organization wants to accelerate application development, then you can go for a public cloud with a PaaS solution. PaaS clouds basically offer fast access to standard, shared services and enables developers to use languages and tools with which they are already familiar.
Private Clouds are basically known for the exclusive use of the organization, operate within the corporate firewall, and are managed by the IT department or a service provider. If your company wants to add new application functionality or switch aging legacy applications, then you can adopt these applications in a SaaS model.
Hybrid cloud basically allows applications to run across both public and private clouds, so the clouds must support standards for application transportability and interoperability. IaaS is a good model for hybrid clouds as it provides the most essential and most flexible services for computing, storage, and networking.
Weighing Up the Cloud Computing Options
Before opting for a public, private or hybrid cloud, companies first need to decide what they are hoping to attain. In Private clouds, everything is hosted on premise, built on the organisation’s resources and data center investments, and leave the company in total control which means the company covers all the overhead costs. In the public cloud, expenses are covered by the cloud provider, but the trade-off here is that a certain amount of control is sacrificed. In a hybrid cloud model sees the costs being divided between the two models. Before adopting cloud computing, companies need to assess how sensitive their data is. Financial institutions, medical entities and such like, who want to gain the advantages of cloud computing without relinquishing control of their confidential data, would be better served by a private cloud model.
The Private Cloud Option
Private clouds basically exist within the business’s firewall, giving it full control over its data: who can handle or access it, where it resides, and how it is transferred and stored. Companies who handle highly sensitive third-party data would be better served by going the private cloud route. Private clouds are made specifically to a company’s needs. These clouds do not provide the same savings those public clouds. In private cloud computing, there is no danger of vendor lock-in, and resolution can be prioritised according to the needs of your business
The Public Cloud Option
A public cloud is the cost-effective cloud solutions, and there is no capital outlay for the hardware and so on that is needed to run a private cloud. It owns all the hardware and infrastructure, and primarily leases it to companies, which can go up or down as necessary, so there is no wastage at all. In public cloud computing, companies will always have access to the latest technologies as the cloud provider will upgrade; and they don’t have to pay for new hardware and infrastructure themselves.
The Hybrid Cloud Option
Most organisations end up opting to go the hybrid cloud route as it comes with both private and public clouds benefits. In a hybrid cloud, the company uses its own dedicated hardware and infrastructure to handle proprietary and confidential data, while using a public cloud for less sensitive and public data. This model relies on location-independent IT where workloads can run in the most appropriate environment, whether locally or off-premise – whatever will be most valuable and relevant. The hybrid model also supports self-service allowed rapid resource provisioning for managers and application developers who need instant access to localised IT resources, as well as those that are held off-premise.
Today, many providers give cloud computing services. So choose the best type of cloud computing services for your company.
