7 AWS Lambda Use Cases to Start Your Serverless Journey
The rise of serverless computing has completely transformed how cloud application developers design and deploy their work. AWS Lambda, a serverless computing technology offered by Amazon Web Services, is at the vanguard of this transformation. AWS Lambda offers a scalable and economical solution to execute functions responding to multiple triggers by enabling you to run code without installing or managing servers.
This post will discover 10 real-world AWS Lamba use cases highlighting its possibilities. AWS Lambda has demonstrated its worth in various contexts, from data processing to automation and beyond, making it a crucial tool in the arsenal of the modern cloud developer.
What Makes AWS Lambda Different?
AWS Lambda reduces operating expenses and complexity by doing away with the need for traditional computing services. Numerous benefits result from this, including streamlined operational management, scaling, and reduced operational costs.
Additionally, Lambda takes care of any frequent fluctuations in memory use. It uses a "Pay as you go" payment approach, with execution time and memory usage rounded to 100 milliseconds. It is a significant advancement over EC2.
AWS Lambda Use Cases
Let's describe each AWS Lambda use cases using real-world examples and its advantages to development teams and companies.
Making Serverless Websites Work
Using both services to manage the hosting and content for your website is a terrific way to take advantage of the price model that AWS Lambda and S3 provide. Through Lambda, audiences on the desktop can communicate with a web server utilizing API Gateway HTTPS endpoints. For use cases where NoSQL is preferred, Lambda may manage application logic and data storage in RDS for usage as a relational database service or DynamoDB for those who prefer to continue with it.
Conversion of Documents in a Flash
Your users might only sometimes be satisfied with an HTML page if you supply documents. While many people prefer an HTML page to see papers, others might want to download a PDF copy of the same document or require a different format for a specific distribution strategy.
You can keep various copies of your papers in various formats so that they are available for people to access. However, maintaining static content can take up a lot of room and is impractical if it is subject to regular change or user interaction.
Utilizing an AWS Lambda application, which enables you to deploy apps with event-driven architecture instead of conventional server-heavy, multi-tiered applications may be more accessible. When a response is required, such an application can quickly obtain the needed information and output it for display or download in almost any manner you see fit, depending on your objectives.
Video Editing
It has been observed that businesses frequently keep thousands of files for hundreds of hours. File storage polling is a procedure that runs on an instance and occurs regularly, much like when files are kept in an S3 bucket. The issue for most people is when movies are constantly posted throughout the day, drastically cutting down on idle time and wasting money and computing resources.
You can use Lambda to upload a script to the cloud and specify the event that will cause the script to run. Anytime someone submits something, a new bucket is generated, and when that happens, the trigger notifies an S3 file to start your operations. The information can then be distributed whichever you like from there! This conserves resources because using fewer resources to do more results in having more resources available for other uses!
Daily Actions and Backups That are Automated
When it comes to performing regular maintenance or scheduling backups, some AWS hosting has to be automated. Lambda steps in when it comes to handling this and ensuring that all AWS services operate well at all times. Virtually any job one carries out in AWS, including automated backups. In AWS accounts, scheduled Lambda events are excellent for monitoring data.
Disaster Recovery
A disaster recovery plan can be built using AWS Lambda in many different methods. Making a backup before changing the primary data center settings, such as updating code, jar files, or database tables, is recommended. When creating EC2 instances, for example, Lambdas can be used with other AWS products, such as EBS snapshots and AMI generation via S3, to back up your resources automatically.
Every disaster recovery strategy would have a primary and secondary data center. To construct an instance of the new code running on the secondary data center, you might execute the scripts after uploading the new code to S3 and using a Lambda function to copy that data.
Security Alerts
Do you fear someone may have accessed your cloud infrastructure and taken some data? Is keeping a close eye on any unexpected activity one of your overall cloud strategy's primary objectives? Being as watchful as you can, which Lambda can assist you with, is the finest thing you can do. Our serverless computing platform, AWS Lambda, allows you to create code to notify a specific person by phone or email when an event occurs. We might configure our function to alert the administrator right away whenever one of the static website files stored on S3 has perhaps been downloaded by an unauthorized person.
Utilizing Outside Services
Sometimes, it is necessary to link the functionality of a third-party contract to the code if your website or application uses outside services. In reality, code is one of the main reasons web-based services take longer to load, especially if they were created with PHP.
If you delegate requests for tasks like credit authorizations or inventory checks to an AWS Lambda-powered application, your main program can carry on with other aspects of the transaction while it waits for the Lambda function to respond.
This implies that a slow response from the provider will often go unnoticed by your clients because they won't see the transaction moving forward; instead, it will end abruptly because your primary application will keep running while it waits for the provider to answer.
The catch to this solution is that you are only required to pay Amazon DynamoDB (or whichever service you're using) if there is activity, so you might theoretically accrue charges when transactions take longer than planned.
Conclusion
These AWS Lambda use cases highlight serverless computing's adaptability and capability. Lambda functions are a crucial tool in constructing and automating contemporary cloud applications since they are created to be highly scalable, affordable, and simple to maintain.
AWS Lambda is a gateway to a new era of serverless application development, not just a technology. You may turn your ideas into reality by utilizing the power of Lambda and working with an experienced AWS developer, ensuring that your cloud-based apps are productive, economical, and prepared to scale with your expanding organization. Therefore, hire AWS developers without hesitation to maximize the capabilities of AWS Lambda and confidently start your cloud adventure.
