AWS Cloud Architecture Explained
An AWS cloud architecture involves multiple AWS services working together to achieve secure, scalable and highly available application systems. Rather than needing a single server or set of data centers, companies can distribute their applications and workloads across several services and Availability Zones.
Common AWS services in an architecture could include a DNS solution like Amazon Route 53, Amazon CloudFront for content distribution, and an Elastic Load Balancer which distributes traffic to either a set of EC2 instances or a container based application for application processing and a database like Amazon RDS or DynamoDB. Systems built in this way can be composed according to performance, security and availability requirements.
AWS cloud can also be used to architect solutions with separate parts for the application. An application, for example, could use one service for presenting the user’s interface, another service to handle the business logic of the application and a third to persist or manage the data within the application.
AWS for Small and Medium-Sized Businesses
AWS is not only suitable for large enterprises, but can also be utilized by small and medium businesses to run infrastructure without spending large sums on their own dedicated server equipment.
You can start your business with a smaller amount of equipment and scale accordingly as the amount of traffic, customers, and requirements increase. A small business might begin by running its website through AWS, store its product image within S3 with static files being delivered through CloudFront and running a database with an associated manageable database.
AWS for Startups and New Applications
It’s common for a startup to want to get a product into customers hands as efficiently and inexpensively as possible. The variety of services available with AWS can enable them to experiment, prototype and develop an application, and then scale up a successful application. Developers want flexibility, ability to take quick action, and the tools required to deploy applications quickly to customers while maintaining control.
When you don’t need a traditional, managed server AWS Lambda can provide another way of running application code in a way that doesn’t depend on managed servers. The AWS service with containers might be useful if you desire finer control over the applications deployment environment.
In addition to services for building applications, we can offer additional services such as Amazon RDS-driven databases, Amazon CloudWatch provided monitoring, AWS service integration toolsproviding, and the development resources for implementing those components.
Utilizing the AWS managed services can enable small teams to continue working on the product instead of maintaining infrastructure components such as servers, databases, networks, and storage systems.
AWS and Serverless Computing
Serverless is a component of any cloud architecture. The term “serverless” may be deceiving, as serverless applications do run on top of a physical or virtual infrastructure, yet AWS takes on much of the responsibility for server administration for the user. AWS Lambda is a popular service for serverless applications. Using Lambda, users can deploy small functions, which are triggered to run in response to an event or other application event, such as an API call, a file that is uploaded, an operation within a database, or a similar event.
Serverless applications are capable of lowering the total infrastructure operational responsibility, and can also allow your system to scale to meet your application workload needs.
However, businesses should consider limits, application structure, performance monitoring, security and costs before moving towards using a serverless application architecture.
AWS Containers and Microservices
Containers package and isolate application code and all its dependencies (like libraries and tools) into a single unit that can be run anywhere your laptop, a private data centre, or the cloud. AWS offers services and tools for running containers-based applications, such as Amazon ECS and Amazon EKS. Microservices are used to break up an application into small services so that they can be built, deployed and scaled independently.
For example, the different components of an e-commerce application such as a shopping catalog, the accounts and payments, or the shipping operations could each be run as separate microservices.
AWS’ cloud services offer a full range of the underlying infrastructure and managed services needed to enable these architectures. Also, containers assist dev teams keep the dev, testing, and production environments in sync.
AWS Data Analytics and Big Data
Companies produce huge volumes of data from websites, apps, transactions, IoT devices and business systems and AWS offers a wide range of services to collect, store, process and analyze data. Amazon S3 can be a go to central layer to put data in. From there it can be pushed to various analytical processing services to be transformed and analyzed.
Data warehousing and analytical workloads will often use Amazon Redshift, other service will be used to handle large scale processing and streaming.
This enables companies to pinpoint customer behavior, track performance of operations, plan for future demand, make better, data-informed decisions.
AWS Backup and Disaster Recovery
Another use of the cloud in an organization is disaster recovery. The cloud provides the services and design elements required to meet organization’s needs in the event of an incident in which operations are disrupted by a hardware problem, cyber event, accidental data deletion, software error, or a natural disaster.
The cloud is able to copy and store data, and create architectures that use multiple Availability Zones to provide a recovery location. Recovery objectives, retention requirements and testing intervals should all be addressed as part of a comprehensive disaster recovery solution.
AWS Cost Optimization
Capital expense is a great advantage of using cloud computing but companies can no longer become complacent on their cloud expenses. Idle compute resources that continue running can accumulate a steep cost in time.
There are different mechanisms for managing expense on AWS, in practice, organizations can optimize instance size, terminate orphaned resources, leverage cloud cost management tools and take advantage of pricing models where predictability matches your usage profile.
Don’t just focus cost optimization after seeing enormous bills, start it with architectural design stage. Development teams need to set up budget alarms, watch resource consumption to look out for anomaly, monitor overall resource utilization.
Optimize cloud environment not necessarily about reducing the amount of money that is spent but to maintain appropriate balance on performance, availability, security and cost.
AWS Monitoring and Performance Management
Applications, resources and services require monitoring, organizations benefit from being able to gain visibility into how applications and infrastructure is behaving. For the purposes of monitoring operational events, metrics, logs and alarms, AWS has services available, such as Amazon CloudWatch, available for your organizational use.
From your application, it’s possible to monitor a range of metrics including CPU usage, application functions, network activity, and error rates, with alerts being triggered by predefined metrics or threshold alerts.
Effective application, and environment monitoring, is key for organizations that have deployed large cloud solutions comprised of a growing number of applications and services, the centralized visibility allowed through monitoring facilitates proactive identification of issues before a large number of your customers encounter problems.
