We have made several API's with the zend framework but due to large data amount we have to use AWS Elasticcache
There is two types of services available Redis and Mem-cached
Mem-cached is suitable for my api but i have did the several research on it for php integration
also i m so new to this environment also so i never got appropriate answer from web
So please help me to understand the Flow of Working with AWS ElasticCache Mem-cached
-> from where we can start
-> what Resource needed ?
-> what are the things we have to download and install
-> and to implement in Existing API url what are the things we need to change and do a code (From where we can start)

I am looking for a language / framework or a method by which I can build API / web application code such that it can run on Serverless compute's like aws lambda and the same code runs on a dedicated compute system like lightsail or EC2.
First I thought of using Docker to do this but AWS Lambda entry point is a specific function signature which is very different than Spring Controllers. Is there a solution available currently?
So basically when I run it in lambda - it will have cold start issue, later when the app is ready or get popular I would like to move it to a EC2 instance for better performance and higher traffic load.
I want to start right in this situation so that later it can be easy to port and resolve the performance issue's
I'd say; no this is not possible easily.
When you are building an api that you'd want to run on lambda's you most likely will be using an API Gateway which takes care of your routing to different lambda functions (best practice). So the moment you would me working on an api like this migrating to EC2 would be a nightmare as you would need to rebuild the whole application a more of a monolith application which could run on EC2.
I would honestly commit to either run it on EC2/Containers or run it on Lambda, if cold start is your main issue with Lambda's you might wanna look into Lambda Snapstart for Java or use another language like Typescript/Python.
After some correct keywords in google I finally got what I was looking for, checkout this blog and code library shared by AWS which helps you convert the request and response of the request as per the framework required http request

Thanks Ricardo for your response - will do check out Lambda Snapstart for sure and try it as well. I have not tested out this completely but it looks promising to some extent.
I have a pretty complex backend project that I deploy to AWS using the Serverless framework. The problem I'm facing is related to versioning. I have a React app on the FE, which has a version on it, but I didn't add a version to the BE for simplicity (it is the same app, I'm not exposing any special API so didn't want to deal with versioning matrices between the FE and the BE, backward compatibility, etc..) --> Is this a mistake?
When I deploy my BE code, AWS does keeps track of the deploy calls and adds versions in the Versions tab of the Lambdas page, and it has a Description property. I'd like to access that Description to at least have an idea which code is running at any given time.
I was looking at the serverless docs and couldn't find a way to send a Description up to AWS. I'm calling it like so:
serverless deploy -s integration
NOTE: I don't have CI/CD hooked up yet, but the idea would be that only checkins to a specific branch (master or develop) would do a deploy to AWS (as opposed to doing it manually on a feature branch while developing). Is this something anyone is doing?
Any thoughts and/or ideas on versioning serverless backend are appreciated.
I currently have aws dynamodb (port: 8000) and elasticsearch (port: 9200)+kibana(port: 5601) running locally.I pretty much spent almost half a day figuring out how to sync these services together. To provide context, I have a nextJS app running thats integrated with both clients however, when I upsert data into dynamo, Id like to get it synced with elasticsearch right away.
Note, for upper environments I plan on using aws lambdas integrated with dynamodb streams to update indexes in elasticsearch instances (I am not a fan of the aws elasticsearch managed service).
Here is what I have tried thus far for local env syncing:
Logstash w/dynamodb plugin (https://github.com/awslabs/logstash-input-dynamodb) - the repo hasnt been updated in 4 years and issues support newer version of ES. Been a headache all morning trying to get the thing running due to this and other issues --> https://github.com/awslabs/logstash-input-dynamodb/issues/10
result: its a lost cause as far as I know... ive even tried their docker images but not workin..
node-scheduler: oh jeez... given Im using nextJS Id have to create a custom server just to get this extra piece synced... not to mention it removes a lot of the important features of nextJS -> https://nextjs.org/docs/advanced-features/custom-server
host the development dynamodb in aws (not local) + provision ES on ec2 and point local app there. I think this is overkill imo as now pretty much everything is hosted except my app, which could be ok. Let me know your thoughts as I already have dev environment using a separate cognito pool to authenticate.
Just chain ES calls to any updates made on dynamodb. Can someone tell me why we cant do this locally and in general? I get that data can get out of sync but maybe we can do hourly, or even twice a day (offpeak) cron jobs to bulk update the dynamo records to ES.
Would really appreciate your thoughts. Thanks!
Ours is a Spring-Boot based application. For integration with AWS SNS and SQS, we have couple of options:
Use Spring-Cloud-AWS
Use AWS-SDK-Java 2
I wanted to know if there is any advantage in using one or the other.
When I ask AWS guys, they tell me that AWS SDK gets updated regularly and integration with SNS and SQS is not difficult. Hence, there is no need to integrate with Spring-Cloud-AWS.
I tried searching on gitter channel for Spring-Cloud and could not find any relevant information. Documentation does state that I can update the AWS-SDK version. Documentation does not state any compelling reason for not using AWS-SDK directly.
If anyone has some insights, please share.
From the AWS Spring Team:
"From now on, our efforts focus on 3.0 - based on AWS SDK 2.0."
So, if you need AWS SDK 2.0, you probably want to go directly with the SDK.
https://spring.io/blog/2021/03/17/spring-cloud-aws-2-3-is-now-available
For more on what's new on AWS Java SDK 2.0:
https://aws.amazon.com/blogs/developer/aws-sdk-for-java-2-0-developer-preview/
The main advantage over the AWS Java SDK is the Spring style convenience and head start we get by using the Spring project. As per the project documentation (https://cloud.spring.io/spring-cloud-aws/reference/html/##using-amazon-web-services)
Using the SDK, application developers still have to integrate the SDK
into their application with a considerable amount of infrastructure
related code. Spring Cloud AWS provides application developers already
integrated Spring-based modules to consume services and avoid
infrastructure related code as much as possible.
Been searching for the last few days for an alternative to the AWS Console Web ui.
We want to give this to our employees to manage their development/test environment their self without interaction from the IT team.
What we want is an extra Web ui that does the following "management tasks"
List all instances (maybe based on tags)
Stop / Start instances
Create / Destroy instances (from specific AMI's)
Also we would like to have logs + authentication (preferable LDAP)
I found a few but none of them actually was that simple.
We would also prefer to have a django/python based application but sinatra is also fine.
Alternatives that I found:
Asgard from netflix
Spurios (has no EC2 instances)
We also found Flask app builder to build our own app but it would be nice if some things already exsists. I believe many company's want the same but are they keeping that for internal use only ?
Maybe you know more projects that I, for some reason, did not stumble on.
