I looking for an AWS environment architecture where I can have more than 500 VPC. I do not see any AWS documentation where it has mentioned the VPC limit per root AWS account. From VPC FAQ it is clear that one account ( not root account ) can have only 5 VPC. Is there a limit for a number of VPC?
I am looking for AWS multi-tenant service where I may have 500 tenants if the business grows. Just want to be in the right direction before designing single VPC per customer/tenant. I am new to AWS and any help is appreciated.
Thanks
Sas
The account limit for vpc per region is 5. Its for the root account only.
Please check the respective docs from amazon aws at Amazon VPC limits
But, you can still ask for increase of VPC by creating case at:
Create case for increase in vpc limit

I am new to the Kubernetes echo system. I have a use case need to pull Kubelet binary version of the Cadvisor metrics data into external storage like S3, Bigquery, or ABS in Azure. Our use case wants to keep it as long-term storage and not enable the Prometheus service in the cloud provider. Is there any way to do it? Thanks!
Try standalone Cadvisor to output the metrics. However, our use case needs the binary version of Cadvisor in Kubelet.
For example, instead of curl the api server
kubectl get --raw "/api/v1/nodes/<node-name>/proxy/metrics/cadvisor"
I would like to know if the metric point can be published passively into S3 bucket.
if you want just one pod info:
You can send a proxied request to the stats summary API via the Kubernetes API server.
/api/v1/nodes/minikube/proxy/stats/summary
if you want all pod info:
use heapster

I launched a t1.micro instance running Apache and MySQL servers on Ubuntu. Basically I'm using it to host my photo sharing app that may have huge random spikes in terms of visitors.
How does AWS go about it?
Will the instance automatically upgrade to appropriate horse power to keep up with demand and growing storage demands?
No, you have to manually make your instance more powerful by first making sure it is in the stopped state (this requires EBS volumes or you'll lose your data), then going to the AWS console, right click your instance and select 'Change Instance Type'.
If you are interested in a more automated approach, I suggest an Elastic Load Balancer with an Auto-scaling policy. With Auto-scaling, Amazon will spin up or down new instances based on set points that you provide (i.e. CPU usage reaches 80% for 10 minutes).

We can see spot price for different availability zones in a specific region in the EC2 web console. However there is only one price shown on the official web site for a specific instance type in a specific region. What is the relationship between spot price that is displayed on official site and the these shown in the web console (for different zones)?
If you are referring to this page: http://aws.amazon.com/ec2/spot-instances/
Amazon states: 'The following table displays the Spot Price per Region and instance type (updated every 5 minutes). In addition to Linux/Unix and Windows, we also offer Spot Instances for Amazon EC2 running SUSE Linux Enterprise Server. Spot Instances are not currently supported in the AWS GovCloud Region.'
You can select the region using the drop down selector. The prices are updated every 5 minutes.

I was wondering if any of you know an Amazon version of cloud sites from rackspace. I know they have services similar to cloud servers and files but not this?
Basically, I'm looking for a scalable web server managed by them, *** but (this is what cloud sites can't do) I want to still be able to do things in the backend and install other apps etc.. (like my own server)?
thanks
Amazon does not offer any managed hosting services. What they provide is infrastructure-as-a-service, the barebones level services for building on top of. They offer no management services. This stuff is meant for low level developers / system administrators to build the higher level systems on, not your average web hosting customer.
Amazon's new Elastic Beanstalk offers something closer to Rackspace Cloud Sites, but is currently limited to Java sites.
I have a new Platform as a Service (SaaS) in the works to offer multiple languages/frameworks on top of AWS to the general public. Check it out...

we have a large ec2 instance running in asia pacific region.we want to reserve that particular instance.In aws management console we see an option to purchase a reserved instance but there seems to be no option to change this instance into a reserved one.Are we missing out on something
Reserved instances are a billing feature, not a technical feature.
You can purchase a reserved instance and the discounted hourly rate will apply to already-running instances, without needing to do anything to them.
Just make sure the reserved instances you purchase are:
- in the same availability zone as your already-running instances
- of the same instance type (m1.small, c1.medium, etc) as your already-running instances.
As soon as the reservation cost clears your credit card you will see the discounted hourly rate take effect for your already-running instances.
Amazon's docs could be a lot clearer on this.
http://aws.amazon.com/ec2/reserved-instances/#4
The AWS's official docs state that the availability zone must be the same. The region is, for example, us-east-1. The AZ is us-east-1a. So, according to AWS, it has to be specific to the last letter.
However, some clever folks found a potential work-around that uses EC2 Consolidated Billing and combines the (odd?) feature that one's us-east-1a might be another us-east-1c (I guess the idea there is to enforce some homogeneity around the AZs).
