There are two major offering of cloud computing environment by Amazon through AWS and by Rackspace through Rackspace cloud. I wanted to know more about What are cons/pros of one platform over other. That will help me in deciding platform for my future applications.
Please see some of these links to better analyze & understand the difference between Amazon Cloud Server with Rackspace Cloud.
Things come into my mind:
Amazon server stack has CHOICES possibly everything, but Rackspace server stack is fixed.
Control everything on your server stack with Amazon but Rackspace - NOPE.
You can play around with various services (EBS, EIP, S3, etc) in Amazon server to suite your price, you can't with Rackspace, since you are priced for the whole stack.
In Amazon - single EBS AMI, you can have many different instance types of machine.

Can somebody please recommend some sources on how best to approach refactoring a legacy AWS infrastructure? That is, how to reduce downtime, optimally migrate data stores (such as DynamoDB or S3), etc. Thanks in advance!
There are a number of approaches you can take to do this.
AWS have a lot of great resources on "migration", as an initial thought take a look at the 6 Strategies for Migrating Applications to the Cloud. Whilst you're already in the AWS Cloud it is a great time to evaluate whether you have anything you can replace or is no longer needed.
There are a number of services that assist with migration, for migrating data stores take a look at the below 2 services which might help to migrate most of your data needs:
Database Migration Service
Data Pipeline
Other services such as S3 you would need to migrate to another S3 bucket, as buckets are uniquely named. If you want to keep the name you will need to delete the origin bucket first. If it is being served publicly try using a CloudFront distribution and then switching the origin to the new S3 bucket afterwards.
For architecting your new infrastructure take a look at the AWS Well-Architected Framework.
There are a number of migration whitepapers that AWS has also produced, some are specific to particular technologies and some are more general.

I am trying to develop a Spring Cloud microservices using Spring MVC and Spring boot. And I would like to deploy in AWS cloud. When I exploring the AWS I found the computing service EC2 and Storage services EBS and Elastic Beanstalk. I found that when creating EC2 getting a default EBS volume.
Here my doubt is that when I deploying my Spring Cloud microservice in Tomcat environment. I also need to create a RDS instance for my microservice, can I choose S3 as storage?
And also I need to deploy my Angular 2 application using S3 and static web site hosting method. So can I use separate buckets for both microservices and Angular application hosting?
I am new to AWS and cloud service platform.
On S3 you can save files; its more like extensible storage as a sevice.
RDS is like RDBMS as a service..
Surely you can use separate buckets ; or different folders in same buckets.

We are getting ready to deploy a new app in the Amazon cloud, using EC2, RDS, and elastic load balancers. RDS would be sharded. Looking at the difficulties of manageing and monitoring anything beyond a few servers, one can see how quickly the task could become pretty crazy. Amazon's interfaces allow you to do all this, but we would have to script it all ourselves.
I was wondering what others have done. There is RightScale, for managed solutions. Has anyone found any other companies, or open source frame works, that do this kind of thing? Looking at:
Monitoring EC2, load balancers, RDS.
Spinning up new instances of the above automatically on predefined load levels.
Sending alerts and taking resources offline automatically when thesholds occur.
Promoting new software/upgrades in PHP and MySQL.
Taking numbers of servers offline for maintenance/troubleshooting.
Any thoughts would be much appreciated.
The type of services you are looking for - automated provisioning, scaling in/out and monitoring is generally referred as PaaS - Platform as a Service. The idea is that you submit your application to the PaaS system and it manages the complete life-cycle of your application.
There are several PaaS providers available that might fit your needs. There's a comparison available here: Looking for PaaS providers recommendations
You should consider your requirements carefully and see which provider is right for you in terms of:
Cloud Support: Do you need just EC2 or maybe additional clouds?
Language support: Some providers target specific coding frameworks and languages
Support
Pricing
Open/Closed source
Disclaimer: I work for GigaSpaces, developer of the Cloudify open-source PaaS Stack.
You could have a look at scalr. They offer this services on their own platform but you can also download the software they're using and set it up on your own.
After Amazon EC2 they started expanding into other cloud services as well, so you can run your scalr managed instances on literally all huge cloud providers.
Very feature rich, but so far I haven't tested it by myself.
You could try Xervmon. They offer integrated cloud management suite of tools to deploy, manage, monitor Amazon AWS along with several other providers. They do offer managed services as well.

Recently I have switched my hosting from bluehost to amazon ec2. I need to know, how my application would be able to send the emails from amazon ec2? Do I need to install any smtp server on my instance or I have to configure amazon SES? Please help.
thanks in advance.
Noone gets to send email directly out of EC2 without signing up to SES and working within its constraints. Good grief, AWS would just be one enormous and thoroughly blackholed spam factory without SES in place.
Might also be worth looking at whether AWS's SNS might be a better solution for whatever you're trying to do.
Update: it is possible to send email directly from AWS, but you'll want to let AWS know by filling in a form so that they can whitelist the IP.
Update: More up to date treatment of this topic in this question.

Ive been delving into the world of AWS and, with very little server management experience under my belt, I'm quickly getting lost!
I'm looking at creating a system that uses Route 53, Elastic Load Balancing, EC2, RDS, S3 (possibly with CloudFront as well) so I can host a user generated content website that also streams video.
So Ive been looking at the following books:
Host Your Web Site On The Cloud: Amazon Web Services Made Easy
Programming Amazon Web Services: S3, EC2, SQS, FPS, and SimpleDB
Programming Amazon EC2: Run Applications on Amazon's Infrastructure with EC2, S3, SQS, SimpleDB, and Other Services
If I had to go for one of these what would you recommend?
Most importantly are there any resources you can recommend for a newbie like myself to quickly learn and understand the nuances to AWS?
TIA
Although all of those resources are good, the best way to dive into using AWS is in my experience CloudFormation. With CloudFormation you are able to script most if not all of your AWS resources in a single json script. By writing your cloudformation scripts and looking through the documentation and sample scripts, you will start to get aquatinted with how all of the AWS toolsets work.
Most importantly are there any resources you can reconmend for a
newbie like myself to quickly learn and understand the nuances to AWS?
As mentioned above, CloudFormation
However to make sure I answer your question:
If I had to go for one of these what would you recommend?
I have read all 3 resources listed and I found Programming EC2 to be the most useful in understanding the AWS toolset
