In just the past twenty years, cloud computing has dramatically altered the way that most businesses manage their data, IT systems, and resources. Previously, an organization had to develop its own on-site IT infrastructure which meant renting a data center, paying upfront costs for new equipment and having experienced employees on full-time payroll to maintain applications. For small and medium-sized businesses, this meant a substantial financial requirement.
Often, people wonder can cloud technology use the provider’s infrastructure or if they will still need to purchase expensive hardware. It can depend, however, for the most part, cloud computing allows organizations to store their data and access applications via the provider’s infrastructure and related capabilities from third-party providers such as Google Cloud Platform.
Cloud infrastructure includes all software and hardware needed to support the cloud services provided to the client. The three main physical components are servers, data storage, and networking equipment.
Three widely adopted cloud architecture models – public, private and hybrid. Each uses the same essential components to provide computing services.
Public cloud is third party service providers that provide cloud resources over the internet to paying clients. Their multi-tenant model allows the lower cost of computing and data storage by leveraging economies of scale. While it offers lower cost computing resources, some organizations, especially those that deal with sensitive data may have privacy concerns.
With the private cloud model, cloud infrastructure is accessed by just one organization. Often, private cloud architecture will be developed and maintained by a Managed Service Provider or on-site staff.
Hybrid cloud computing is a mix of private and public cloud systems that interact with each other in a separate, private system. This is a popular choice for businesses that need to maintain data privacy or industry regulations by storing some data on servers on-site. Less sensitive information and applications can be hosted in the public cloud, with lower costs. Typically, when an organization chooses a hybrid cloud model, they or a Managed Service Provider will maintain the environment.
There are three main types of delivery models for public cloud services: IaaS, PaaS, and SaaS. Each method varies in what components of the technology stack are outsourced along with what the client provides.
Infrastructure-as-a-Service model – The cloud provider will deliver data storage, servers, virtualization capabilities, and networking. The client has access to as much storage and computing power they need but have to use their own software platform, like an operating system, to run it.
Platform-as-a-Service – The cloud service provider delivers the full infrastructure including data, virtualization, networks, and servers along with a software platform that includes operating systems. This model is designed so that clients can develop, test and deploy their own applications in the cloud without the complexity and financial burden or building their own on-site infrastructure.
Software-as-a-Service – The cloud provider delivers an application via an internet-based portal. With this model, clients do not have to store the application on their personal hard drive, instead, the data is stored on the service provider’s servers. SaaS providers are responsible for the entire technology stack, from maintaining the physical infrastructure to supporting the application itself.
