Utilizing cloud solutions for seamless scalability while awaiting increased workload thresholds
Pros and Cons
- "Lambda saves me time in configuration and deployment and gives me confidence in its high availability and scalability."
What is our primary use case?
I use AWS to host our app space within my university, APU. My infrastructure is based on the AWS cloud, and most of my compute workloads are primarily based on Lambda. This setup facilitates all transactions that require engagement from multiple stakeholders, including staff, faculty, students, and administrative staff. I have in-house applications, both mobile and web-based, that engage with Lambda to provide the required scalability, especially during peak hours of university timings. Lambda is a highly utilized service for me.
What is most valuable?
The most important feature of Lambda for me is that I don't need to manage any resources. I don't have to set up an AWS stack or developer tools, as they are provided by AWS by default. This means that if I need to set up Lambda, it's a matter of minutes to deploy my code, which facilitates my CI/CD pipelines. Time is an important optimization for me, and Lambda is economical. Additionally, it is highly available and sustainable, unlike EC2, which is a single point of failure. Lambda saves me time in configuration and deployment and gives me confidence in its high availability and scalability. I have done my workload migration from an on-premises environment to the cloud, significantly reducing my capital expenditure. The automation improves my planning for product releases and hybrid connectivity. Also, content delivery has improved, and application latency has decreased.
What needs improvement?
I would say an increase in the current limits would be quite beneficial. Right now, the threshold is fifteen minutes. AWS has increased the limits from three to ten gigabytes, enhancing the productivity of different workloads. If this threshold is extended further, more workloads currently utilizing EC2 could potentially be executed using Lambda.
For how long have I used the solution?
I have been working with Lambda since 2018.
What do I think about the scalability of the solution?
Speaking of scalability, I would rate this aspect as close to nine out of ten. So far, I haven't had any issues with the usage of Lambda. Since AWS launched its region in Malaysia, the compute is happening right next to my location.
How are customer service and support?
Support is of the highest quality, so I would give it a five out of five.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
Before Lambda, I mainly used my on-premises environment.
How was the initial setup?
The entire Lambda project took less than three months. I'm not the team lead for that setup, so the exact timeline isn't possible for me to provide. Currently, I'm mainly in the training division.
What about the implementation team?
Maintenance of the overall cloud setup involved less than fifty people. They are not only for maintenance, as they are also involved with enhancing other solutions. I would include developers who are creating new products and releasing them. So overall, the staff is around fifty, but specifically for maintenance, there are fewer people.
Which other solutions did I evaluate?
Azure was one of the options during my evaluation, but I decided to go with AWS.
What other advice do I have?
I would suggest newcomers go through the AWS Well-Architected Framework, especially the serverless application stack offered by AWS, such as Lambda. The cloud adoption framework by AWS is quite in-depth, providing many integration points for reskilling and handling workloads. It’s crucial to explore these frameworks before migrating workloads to the cloud. Additionally, looking into AWS CloudFormation for automating infrastructure provisioning is beneficial. I would rate AWS Lambda as nine out of ten.
