The essential component for hosting web applications is the web application server. A web application server serves applications that deliver static and dynamic web pages over HTTP or HTTPS. With increased popularity, Businesses prefer using Cloud computing and cloud services for existing and new web application hosting environments.
For a cloud server to provide a reliable, scalable and high-performance service, it needs a host of associated components, including but not limited to content delivery networks, cache servers, file repositories, potent security and firewalls, load balancers. When a business avails Infrastructure-as-a-service (Iaas), it needs to install these components individually. Strategic and engineering consideration is crucial to setting up a viable and cost-effective cloud instance.

Highly Available Cloud computing architecture
A highly available cloud computing architecture that accepts and processes user requests without service interruption. Setting up a highly-available architecture involves numerous components to ensure uninterrupted service.
For a business that handles high magnitude concurrent requests, it is imperative to have a server structure that is highly reliable and highly available.
Essential Components for Highly-Available Applications
Containers: Containers are packages of a web application code with dependencies such as specific versions of programming language runtimes and libraries required to run the application.
Content Delivery Networks (CDN): A CDN or a content delivery network is a geographically distributed cluster of servers that operate together to provide fast web page content delivery. A CDN reduces latency for the user and load on the application by having cached content on the edge servers.
Cache Servers: A cache server is an intermediary, high-speed server that stores and delivers previously requested and computed data. A cache server usually stores session data, front-end components, improving the performance and scalability of the application.
Load Balancers: Load Balancers are virtual instances that effectively distribute incoming network traffic across a server pool - a group of application servers. Visualise a load balancer as a 'traffic cop" who routes requests to servers that can fulfil them. Load-Balancers are essential for high-traffic and high-demand applications.
Auto-Scaling: Auto-scaling is a typical cloud feature that allows businesses to scale up automatically or down server resources based on defined server utilisation or traffic. Auto-scaling provides a cost-effective solution for high-demand applications by scaling up during the spike and down during the drop.
Storage: Storage in the cloud refers to data storage as a service - a cloud computing model of storing data on the internet. There are different types of storage - Object Storage, Files Storage and Block storage. Cloud storage brings down storage ownership costs significantly and allows faster rendering.
Database: Cloud provides a database as a service. A business can set up database servers on virtual machines or opt for database-specialised instances offered by the service provider.
Queues: Queues are service-to-service calls used in web applications to process and delete messages asynchronously. Queues are used in batch processing and to handle requests during a spike.
