Amazon Elastic Compute Cloud (EC2)

EC2 is elastic infrastructure. Your org does not have to invest in in-house data centers and staff to manage the hardware. AWS EC2 provides elastic cloud environment to run lot of this. Price is reasonable and AWS has lot of h/w s/w design pattern to design a reliable software application and run it in a resilient environment.

XenServer is well suited for all scenarios for deployment for a modern infrastructure. The weak link it has is of course for classic physical hardware that has key fobs or other telephony cards which aren't properly supported in a virtualized environment. Even if you have one physical server, virtualizing is the best practice to do.

Pros

  • EC2 makes right-sizing your servers a breeze. You can quickly spin up a server in the cloud and if it turns out the vCPU, RAM, or storage space is wrong, within minutes you can change all of that.
  • EC2 makes backups and restores a breeze. We actually had a client that allowed a hacker to remote into their production server. We were able to shutdown the EC2 instance, spin up a backup from an AMI, and then attach the existing elastic IP. This was all done within a 15 minute window.
  • EC2 makes quickly deploying multiple servers a very easy. Within minutes, you can deploy a whole fleet of cloud servers.
  • EC2 is easy to script. We are able to save our clients a lot of money by scripting their EC2 instance to shutdown/startup at predetermined times so they are only paying for the server when they are using it.

  • Provides visibility of all the VM's and one can tell when any of the server's are offline.
  • The functionality to re-boot a VM is easy and quick
  • It is secure and can be accessed remotely.

Cons

  • Docker style templates for EC2 instances, where the installation, backup and rest of the scripts come out of the box.
  • Ran into a couple of issues while trying to reboot the EC2 instances, doing reboot on the instance through CLI caused data issues on the system. That needs to be ironed out.
  • Costs need to be competitive with rest of the market. Found that EC2's are a lot more expensive than its competitors. So if you are tied into the Amazon ecosystem, then EC2 makes sense, but if you are looking for silo EC2 instances, look elsewhere for cost saving.

  • Front line support form off shore has been challenging lately. Need a better escalation path for issues.
  • Upgrades can be difficult at times. Not always super smooth.

With the knowledge and usage of solutions from VMware and Microsoft offering more compelling cloud integrated options it makes it more compelling in many environments which I consult. XenServer is a good product and fits the bill in many smaller environments but as clients look to the cloud or a hybrid cloud it can in some cases make it a bit more difficult.

XenServer is quite usable due to the simplicity the management and installation provide for an administrator. The console for management is very intuitive and can easily be installed on any Windows operating system. There is a relatively simple web console that can be implemented as well that enhances the usability to provide service to non-administrators.

It's been a little problematic in the past at larger VDI deployments requiring a bit more care and feeding than other vendors. But the latest releases (6.5.x) have brought about huge improvements in the stability and availability.

When running like a top XenServer is a fantastic hypervisor. There is relatively low overhead on the Dom0 so workloads get the most of the resources.

The staff I've worked with are very knowledgeable or able to get a very well articulated and capable support team member on the phone or helping them if necessary and they always want to ensure the best experience possible for you on the platform. The ability for the support team to reach out to hardware vendors for assistance is a nice plus too.

Part of a training for certification to become a trainer for Citrix included an in-person training with a Master CCI. The XenServer training at this time was pretty simplified due to the product primarily being installed however you did have to work with it and mildly configure the system.

Haven't given it a real go with any online training however there are some options out there. I have taught a course following Citrix material for XenDesktop which leverages XenServer and it is pre-built so not the best for XenServer specifically for installation but configuration is mildly touched on

Ensure you review the HCL (hardware compatibility list) and reach out to the hardware vendors to ensure they support the platform and in case they have documentation that can be followed for the implementation. Also ensure the prerequisites are completed prior to implementation so that as few unexpected delays occur as you can control.

Alternatives Considered

When it comes to AWS EC2, the technical aspects are about equal to many of the other cloud services, but where AWS EC2 shines at is its management, and growth capabilities. You can start your web based business using AWS for literally zero start-up costs: you use the same Amazon account you use to order office supplies and your laptops, click a button, and start renting servers that only cost what you ACTUALLY use, which is really revolutionary for the data industry.

XenServer is easier to use and cheaper than VMWare, but there is a bit less industry support. If your aren't afraid to use products from someone besides the market leader, XenServer is a great alternative to VMWare.

The servers latest versions have made massive improvements to scalability. But from past experience there have been issues when running workloads for extended periods of time without reboot on the hosts. I would need to run similar workloads on the 6.5 release which has changed much of the bottlenecks or issues so I'd imagine its far more capable now, Perhaps able to stand near the best in the market.

Return on Investment

  • Since deployment and operational upkeep costs are a critical sales point for my customers, AWS has given me the perfect environment to work with.
  • EC2 is great for performing upgrades. I am able to create an entirely new system, then just quickly move the data over with a few clicks, like moving a hard drive. If something goes wrong with the upgrade then I can roll back to my original system just as quickly. I have averted quite a few disasters due to hardware specifications not working properly, which has given me many stress free upgrades, as opposed to what could of happened.
  • Growth capability is probably the one thing AWS does better than anyone else, which means that pre-launch calculations are not even something I have to consider, let alone worry about. Having a site crash due to success and popularity is one of the worst things that can happen to someone, and I use to put more time and energy into calculating what "might" happen than I would into designing the site itself. With EC2, I can launch my site with a free micro-instance and can rest easily knowing that regardless of how many customers like and WANT to use my site. Automated scaling is a thing of beauty.

  • Positively, the ability to implement a XenServer pool for VDI workloads is a fast process. Thus a faster project getting into the pilot phase.
  • Negatively, XenServer has caused outages at client sites due to the pool master failing and a subsequent member not taking over properly (VDI).
  • Negatively, XenServer has failed to allow easy addition of storage or expansion to a SAN drive which required an outage to occur in order to properly see the new free space for growth.
