Amazon Elastic Compute Cloud (EC2)

It's great to prototype cloud infrastructure, and when you need some very specific configurations. EC2 is well suited to dynamically growing infrastructure based on demand, for self-service environments for your engineering team, and for very particular configurations where other cloud vendors may not have a specific solution. Great for legacy applications.

Citrix Hypervisor

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

  • Leverage S3 for backup, storage, and serve up large files
  • Increased bandwidth
  • Increased speed of deployment
  • Pay-as-you-use pricing model

  • Manages upgrades to the pool of hypervisor hosts with relative ease through a console (if licensed).
  • Makes it easy to create machine templates and clones and move them around within the pool of hosts.
  • Handles failures reasonably well through the use of the pool database copied on each host

Cons

  • There should be an option to upgrade to only CPU and memory, instead of getting overall big instances.
  • Sometime we are forced to upgrade or terminate old instances. They could support old instances.
  • Launch time of the instances has room for improvement. Could be faster.

  • Adding or presenting additional storage to the host can often be a task that is far more involved than competitive products.
  • The product can require reboots more frequently than competitors due to the DOM kernel getting "hung up".
  • Sometimes when a virtual machine is deleted it still leaves behind orphaned vdisks.
  • Recovering from the loss of a host can sometimes cause virtual machines to require lengthy command prompt scripting to fix so they can be powered back on from another host.

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

Compared to other IaaS providers such as Google Compute Engine, EC2 stands out due to its ease of use, good performance, and low price.

Lately, Google Compute Engine seems to have improved noticeably, but we stack with EC2 for the trust and quality that has generated is in the last 6 years.

XenServer like the similar product I've used in the hypervisor market stacks up well in regards to compatibility with virtual machine [operating systems]. It is also capable of allowing for large, powerful VMs to be run upon it. The main selection of XenServer in environments I've worked within was due to the price and supportability it entailed. With a Citrix license of XenDesktop you get the XenServer license included which means direct price savings over competitors (added costs) and a support channel for issues.

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

  • EC2 reduced the need for many specialized personnel for infrastructure.
  • Reduced expenses in acquisition and maintenance of servers.
  • Reduced costs in configuration of development and production environments, due to virtualization, images and volume management.
  • The perception of many clients improves when you work with an ally like Amazon AWS, which translates into contracts.
Miguel Angel Merino Vega profile photo
  • The company saved a lot of money in terms of buying physical servers by using Xenserver it was easily to create VM's
  • It is easy to use and manage, therefore saved on costs of support.
