Secret 3: Exploring Cloud Architecture and Deployment Strategies
Cloud architecture plays a crucial role in designing scalable and reliable cloud solutions. Understanding cloud deployment strategies will help you deploy applications effectively on AWS, ensuring high availability and performance.
Cloud providers offers near-identical services, but the nature of those services can be broken down into three different computing models: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). Let’s take a look at each of these models to see what they offer and how you can leverage them.
Cloud Computing Models
In general, there are three main cloud computing models available from the public cloud providers:
1- IaaS (Infrastructure as a Service)
IaaS (Infrastructure as a Service) is the bedrock of cloud computing, providing instant access to computing resources like virtual machines, storage, and networking components. It’s the entry point for organizations embracing cloud technology.
In IaaS, users tap into resources such as virtual machines and storage via self-service portals, paying for usage only. Unlike traditional setups, the cloud provider handles infrastructure management, letting users focus on resource consumption.
Examples of IaaS offerings include Amazon EC2, Azure Virtual Machines, and Google Cloud Compute Engine.
2- PaaS (Platform as a Service)
PaaS (Platform as a Service) takes cloud computing to the next level by abstracting the underlying infrastructure up to the operating system level. Users don’t need to manage virtual machines or operating systems; instead, they focus on deploying and working with their applications built on the PaaS offering.
This streamlines application development and deployment, increasing speed to market while reducing operational complexity. Examples of PaaS offerings include Amazon Elastic Beanstalk, Google App Engine, and Azure Web Apps.
3- SaaS (Software as a Service)
The SaaS model provides direct access to software for end users without the need to manage underlying software or infrastructure. SaaS applications are cloud-based and accessible via browsers or apps. Users only manage their data, while everything else is handled by the cloud provider. Examples include Microsoft 365, Salesforce, and Google Workspace(aka, G Suite).
Deployment Architectures
In addition to the three cloud computing models covered above, it is also important to understand the main cloud computing architectures available.
There are four main types of cloud computing deployment models in wide adoption today.
1- Private / On-premises cloud
A private or on-premises cloud is often owned and managed by a single entity, like an enterprise organization, for internal use. It combines on-premises IT with features of public clouds, such as self-serviceability and semi-automation for resource provisioning. Private clouds can be hosted internally, in a co-location facility, or with a local service provider. Enterprises maintain control over procurement, provisioning, and administration, offering benefits like granular control and security. However, it often entails high capital expenditures (CAPEX).
2- Public Cloud
The public cloud, operated by large providers, offers a globally distributed IT infrastructure accessed via the internet. It ensures secure multi-tenancy and scalability, reliability, and availability. Users pay on a per-use basis, shifting from CAPEX to OPEX model. It provides self-service and automation, offering various computing models not found in other deployment methods.
3- Hybrid Cloud
Hybrid cloud combines public and private/on-premises deployments, offering tailored IT solutions for different business needs. It balances innovation, scalability, and cost efficiency of public clouds with security and data sovereignty of private clouds. While flexible, hybrid clouds may pose operational complexities, suiting mainly enterprise organizations. Access to both traditional and public cloud resources enhances flexibility for meeting diverse business requirements, driving its popularity among enterprises.
4- Multicloud
The Multicloud architecture combines multiple public cloud platforms (at least two) along with private clouds, offering a diverse set of services managed by different providers. Its primary goal is to avoid dependency on any single cloud provider. While it allows access to best-of-breed technologies, it introduces operational complexity due to diverse platforms and technologies.
