When a business runs its whole IT infrastructure on-premises, it owns the entire technological stack.
When managing up an entire on-premises stack, resources are often limited, leaving responsibilities unmet and exposing security vulnerabilities.
Moving to the public cloud can save your company money by removing the costs of hosting servers and other infrastructure on-premises. Public clouds can also relieve you of maintenance and security responsibilities by transferring them to the cloud provider. That is why so many modern businesses outsource their cloud administration.
While cloud providers provide varied levels of data security, they do not completely protect your customer and company data at any level. They use a system known as the "Shared Responsibility Model," which works precisely as it sounds.
Your supplier shares responsibility for your environment's security, beginning with the physical infrastructure, while the rest is up to you. The provider (typically Microsoft Azure, Amazon Web Services, or Google) is responsible for various components of your cloud, depending on your package.
Anything not covered by the chosen plan is handled by the client, resulting in full coverage in the best-case scenario. Even with the most complete cloud provider packages, your company is still responsible for data security. Account and access management, for example, decides who has access to your data and how they can access it.
Businesses that want to shift to the public cloud can buy directly from the cloud provider of their choice. They can also buy from a reliable cloud service provider (CSP), who can help handle the remaining tasks that your cloud provider does not cover.
In this article, we'll go over what duties the most prominent cloud providers handle, how their service levels differ, and what you need to do to secure your cloud in each situation.
What does it mean to be "on-premise"?
For the purposes of this article, "on-premise" refers to a technology environment that is wholly hosted and managed by the company that uses it. Essentially, it means that the business assumes all duties and does not use a CSP. Keep in mind that a cloud can be on-premise even if the data centre that houses a company's computers is physically located somewhere other than the company's headquarters.
What is infrastructure as a service (IaaS)?
Infrastructure as a service (IaaS) is a form of outsourced service in cloud computing that just provides the core storage and networking parts of the cloud. The most flexible choice is IaaS, which allows you to rent gear while maintaining complete control over it. The cloud provider handles the physical servers that run your public cloud as part of this subscription service, keeping the hardware up to date and safe. An IaaS plan eliminates the costs of running a data centre on-premises and allows organisations to scale globally. All network and application controls, data classification and accountability, and endpoint security, on the other hand, are left to the customer.
What is platform as a service (PaaS)?
Platform as a service (PaaS) plans, in addition to the advantages of an IaaS plan, relieve the strain of some application-level and network control management. Development, business intelligence, and database administration technologies are primarily the advantages. The cloud provider handles virtual machines and network resources in PaaS, while the customer uploads internal web applications to operate on the platform.
What is software as a service (SaaS)?
The complete package for outsourced cloud solutions is Software as a Service (SaaS). It still doesn't cover everything there is to know about cybersecurity. SaaS adds hosted software to the mix, with your cloud provider providing and hosting all of your infrastructure. Employees will now connect to a cloud-connected app, while the CSP will handle all hardware and software updates. With SaaS, the cloud provider handles application-level and network restrictions, allowing the client to handle just data classification, endpoint security, and identity and access management.
