As I detailed in a previous blog post, I’m continuing to update the Linux Academy AWS DevOps Pro certification course. The course has three new sections (and Lambda Versioning and Aliases plays an important part in the Lambda section): Deployment Pipelines. AWS Lambda, and. AWS Lambda and Serverless Concepts.
We use them at Honeycomb to get statistics on loadbalancers and RDS instances. Heres a query looking at Lambda invocations and concurrent executions by function names. Queries like this allow us to see trends in our AWS Lambda usage over time: However, CloudWatch metrics filtering capabilities are pretty limited.
And, of course, all our AWS integrations work flawlessly on Graviton3 which means we’re as ready as ever to continue supporting customers as a Graviton Ready Partner. We’re also very heavy users of AWS Lambda for our storage engine. Based on what we’ve seen so far with Graviton3, there are massive improvements coming your way.
LoadBalancers, Auto Scaling. Lambda – what is lambda / serverless. Lambda – what is lambda / serverless. Course Syllabus. Take a look at these courses , and sign up for a 7-day free trial to learn AWS by doing today. . Route53 – overview of DNS. CloudTrail. and some others.
For instance, you can scale a monolith by deploying multiple instances with a loadbalancer that supports affinity flags. Another option is to avoid services with maintenance overhead altogether and opt for Functions as a Service (FaaS) , such as AWS Lambda or Azure Functions.
A tool called loadbalancer (which in old days was a separate hardware device) would then route all the traffic it got between different instances of an application and return the response to the client. Loadbalancing. Amazon API Gateway — for serverless Lambda development. Let’s discuss how it does that.
While this trend still requires servers, developers don’t need to worry about loadbalancing, multithreading, or any other infrastructure subject. Of course, there are some more advanced configurations like changing the port or customizing the registry and context, but that’s another story for another blog post.
Their expertise in optimizing EC2, S3, and Lambda confirms businesses particular expenses for the resources they indeed need, lowering costs while maximizing performance. Loadbalancing optimizes traffic distribution across instances to maximize resource usage. AWS tools: Auto Scaling Groups, Elastic LoadBalancer (ELB).
You can go blow up stateless applications all day long and you can just loadbalance across new resources all the time. 1 for Datadog, we had done about 160 game days over the course of two years. Our Chaos Monkey was like a Python script in AWS Lambda. It makes this really easy to do. Don’t jump into it.
AWS Lambdas don’t let you do that. If you’re still using an Elastic Compute Cloud (EC2) Virtual Machine, enjoy this very useful tutorial on loadbalancing. That’s what I’m using AWS Application LoadBalancer (“ALB”) for, even though I have only a single instance at the moment so there’s no actual loadbalancing going on.
It took us some tries and discussions to figure out, that there are multiple ways to go (apart from just clicking through web consoles manually of course): Command Line Clients All cloud providers have a command line client, you typically need anyway. Provisioning options So let’s go. Sounds great! as described in more details below.
of course they’d be much happier if you were still locked-in with their physical boxes. and patching, and scaling, and load-balancing, and orchestrating, and deploying, and… the list goes on! They’ll shout about vendor lock-in?—?of They’ll ignore the operational cost of actually running servers?—?and
