Any idea why I don't see the Local option like it's mentioned in the doc?
Thanks #Subin Mathew. I also found out that the local cache is only available upto 8 vCPU instances. The AWS docs don't mention it anywhere.

long time reader but I've usually been able to find the answers I've been looking for in existing posts - but this time I've not been able to.
I am essentially teaching myself AWS CDK from scratch, I've only really just started with it so not finding anything which helps me on my mission may be a result of not knowing enough yet to be asking the right questions... so please bare with me.
Thus far I've used the AWS CDK with Python to create a stack which creates an S3 bucket, and also fires up an EC2 instance with an AWS file storage gateway AMI loaded on it (so running Amazon Linux). This deploys and runs fine - however now I'd like to programmatically set up the S3 bucket to be accessed via an NFS share on the EC2 instance. From what I've seen I'd assumed it is or should be fairly trivial however I keep getting a bit lost in documentation and internet hunts and not quite sure I'm looking in the right places or asking search engines the right questions to unlock the path to achieve this.
It looks like I should be able to script something up to make it happen when the instance is start using user-data but I'm a bit lost. Is anyone able to throw me some crumbs to follow to find a good way of achieving this, or a better way of achieving what I want to happen (which is basically accessing the S3 bucket contents as though they are files on an EC2 instance) - if not tell me how to do it if it's trivial enough?
Much appreciated :)

You are on good track. user_data can be used for that.
I don't have full code to give you as its use case specific (e.g. which OS are you using?), but the user_data would have to download and install s3fs:
s3fs allows Linux and macOS to mount an S3 bucket via FUSE. s3fs preserves the native object format for files, allowing use of other tools like AWS CLI.
However, S3 is an object storage system, and it can't be really mounted on an instance like you would do with NFS or EBS storage solutions. But with s3fs-fuse you can mimic such a behavior. And for some use-cases it will be sufficient.
So what you can do, is to setup the user_data script through console, verify that it works, and then basically just copy and paste to CDK. Its more of a trial-and-see approach, but this is the best way to learn.
I have implemented Redis cache with .net core 2.1 application. Now the issue is I have only development connection string. I want to configure and test Redis cache somehow on my local pc. I have read somewhere that it is possible using chocalatey. So can body refer me any link?
PS: When I tried to run redis cache from development server using vpn, It shown me popup to select "ResultBox.cs" file. So I created new ResultBox.cs file and give it the path, but when I call rediscache.Get() method it opens ResultBox.cs file but nothing happens then. Can anybody tell what is ResultBox.cs for?
I have found a way to configure Redis on local using chocolatey. Use this link. If you face Misconf issues while testing on redis-cli this link will be helpful.
You can run a local docker redis image. See this and this for reference.
I am trying to move my moodledata folder content into Amazon S3. i didnt found any document (or guide) to configure this setup.
I am using MOODLE 3.3 STABLE build version.
Can anyone help me to setup this?
You could use s3fs and mount it on your webserver.
I suggest to use local directory (for performance) to:
cache, localcache and sessions
I've been using riofs for AWS S3 bucket to filesystem mounting on an EC2 instance.
Yes yes, I know... you shouldn't use fuse for S3 mounting as its a leaky abstraction.
With that said, I didn't see anyone else post any questions regarding this issue (specifically with riofs) so I'm posting this question.
Why is it happening and what can I do it fix it?
It looks like fuse doesn't have a stable version past v2.9.7 so that is what I'm using.
s3fs does have an open issue which I'm guessing has the same problem (https://github.com/s3fs-fuse/s3fs-fuse/issues/152).
I have tried adding -o multireq_max=5 as a riofs command-line option without success.
Can someone elaborate more on the details of how to remotely start a EC2 instance remotely?
I have a Linux box set up locally, and would like to set up a cronjob on it to start an instance in Amazon EC2. How do I do that?
I've never worked with API's, if there are ways to use API's, can someone please explain how to do so...
Pretty Simple.
Download EC2 API. There is a CLI with it.
keep EC2_PRIVATE_KEY and EC2_CERT in as your envt variables, where they are private key and certificate files that you generate from EC2 console.
then call ec2-reboot-instances instance_id [instance_id ...]
Done.
Refer: http://docs.amazonwebservices.com/AWSEC2/latest/CommandLineReference/ApiReference-cmd-RebootInstances.html
Edit 1
Do I download this directly onto my Linux box? And how do I access the CLI on the linux box of the EC2 API? Sorry to ask so many questions, just need to know detailed steps of how to do this.
Yes. Download it from here
If you have unzipped the API in /home/naishe/ec2api, you can call /home/naishe/ec2api/bin/ec2-reboot-instance <instance_id>. Or event better set unzipped location as your envt variable EC2_API_HOME and append $EC2_API_HOME/bin to your system's PATH.
Also, try investing some time on Getting Started Doc which is amazingly simple.
