What is cloud architecture?
Cloud architecture is the arrangement and alignment of the components and subcomponents of cloud computing. Usually cloud architecture consists of all components of cloud computing and includes front-end platform, network, servers, data storages and so on. In other words, cloud architecture is the process of integrating individual technologies to create clouds — IT environments that abstract, pool, and share scalable resources across a network. Cloud architecture is the connection of all the components and capabilities required to build a cloud in order to provide an online platform on which applications can run. As if you were constructing a house, cloud infrastructure would be the materials, while cloud architecture would be the blueprint.
What does a cloud architecture look like?
Clouds are Platforms-as-a-Service (PaaS) because a cloud provider provides users with both the platform and the underlying IT infrastructure. Architecting a cloud platform entails more than simply abstracting a computer’s capabilities from its hardware components, which is how providers create and provide cloud infrastructure to users. It also necessitates additional levels of development to incorporate containerization, orchestration, application programming interfaces (APIs), routing, security, management, and automation software. User experience design (UX) is also important in creating a navigable online experience.
While cloud architecture varies depending on what you’re trying to accomplish, most clouds require hardware, middleware, management, and automation software. Virtualization is also used in most clouds to abstract hardware resources into centrally managed data lakes, whereas bare-metal clouds connect clients directly to hardware.
Public, private, hybrid, and multi-cloud architectures.
Public cloud architecture:
A cloud environment built with resources not owned by the end user and redistributable to other tenants.
Private cloud architecture:
A cloud environment that is solely dedicated to the end user, usually within the user’s firewall and sometimes on premise.
Hybrid cloud architecture:
Several cloud environments, each with some degree of workload portability, orchestration, and management.
Multi-cloud is a strategy where an organization leverages two or more cloud computing platforms to perform various tasks. Companies that do not want to depend on a single cloud provider may choose to use resources from several providers to get the best features from each service. Multi-cloud can be a mix of two or more public clouds, several private clouds, or a combination of both public and private clouds.
What is the role and responsibilities of a cloud architect?
Cloud architects are highly skilled IT professionals whose expertise allows to navigate complex cloud environment. Cloud architects are responsible for developing and managing the cloud computing architecture in a company. They design and supervise an execution of a plan that describes how to implement technical requirements into an actual architecture to achieve an expected result. Cloud architect quite often works in a close collaboration with DevOps and software engineers.
