In speaking with many managed service providers over the past several years, I have come across the same age-old battle around sizing virtual machines. Should I size client’s Virtual Machines down when I know that they’re not using what we gave them?
The virtualization morals inside you begin to cringe as nightmares of Ready Queue and Swapping begin to creep into view.
If I am able to hypothetically achieve this desired state, then I should be able to both increase my bottom line revenue while at the same time reduce the cost of running my infrastructure. The hidden challenge that we don’t typically think lies within the trade-offs that MSPs make between performance in the 1st section, and cost of infrastructure in the second. Let’s take a look at Rackspace’s pricing model to illustrate (Disclaimer: I am not assuming here that Rackspace delivers bad performance when these scenarios happen and am simply using their shared model for illustration. Let’s say that I am a hungry customer and I shop for VMs like I shop for cars: I need the biggest, loudest engine, sleek RIMs, and it has to seat 6.
My friends and I start using our bran new SUVs, but there’s a problem: We all live in the same neighborhood and we’re driving across the street to park in each other’s driveways. My users didn’t adopt my usage plan like I had expected and what’s worst is that there’s not enough space in each other’s driveways when we all want to hang out.
The shared resource issue equivalent in a VMWare environment would be things like CPU-Overprovisioning, Ready Wait State, Balloon and Swap. Fit more cars it my driveway by sizing the correct workloads next to the right Tetris pieces in real time. Retain more customers by delivering exceptional service levels and better allocations based on their inflight load.

Each Rackspace instance was powered by an AMD Opteron 4170 HE, a two generations old predecessor to the AMD Opteron 4376 HE processor we recently benchmarked.
We are utilizing our new Linux benchmark suite and Ubuntu Server 12.04 LTS to take a look specifically at the compute performance of these instances. Here the general trend is that the larger instances are providing performance speed-ups in most cases. Key takeaways from the Rackspace Cloud benchmarks are that instance speed does indeed increase as one scales instances. Finding files that are modified or updated by you in the last few days for backup or recovery or simply synchronization. By default, php errors are logged to that file unless otherwise specified by your application.
So as you can imagine, if your application is requiring upwards of 128M of memory just to load a single webpage it probably won’t load very quickly.
Cloud FilesTM, powered by OpenStack®, provides easy-to-use online storage for files and media.

Oftentimes, when a customer complains of their site being defaced or infected with malware, we will investigate and discover that they are using a CMS such as WordPress. The maintenance will impact customers utilizing Cloud Servers, Cloud Files and Cloud Sites.
During the maintenance window, we will be performing an upgrade to our entire Cloud infrastructure.  Please note that throughout this time there will be no access to your Control Panel or the Cloud API. Multiple systems within our infrastructure, including internal support tools, will also be affected.
If you have any further questions concerning this maintenance, please do not hesitate to contact a member of our support team, via chat or via ticket.
Wherein session_name is the saved session name, your_user_name is your SSH login user name and your_password is the password. Linode is probably the cheapest VPS in all unmanaged hosting companies but it’s far from the worst. They also have a very comprehensive documentation library that you could look up stuff in case you don’t know how to do something by yourself. The only down time I experienced was a power outage or something that lasted about 3 hours.
I would recommend Linode to anyone who’s good at managing the hosting server themselves!
In a managed hosting environment, your provider owns and is responsible for the data center, network, devices, operating system and application infrastructure components, providing a stable operating environment for your applications. Managed Hosting provides more value than colocation and dedicated hosting because it frees more of your IT personnel from mundane infrastructure related tasks, personnel that can now be reallocated to understanding and supporting your business more effectively. Managed Hosting also provides greater responsiveness than fully outsourced solutions because it emphasizes a flexible bottom-up approach to delivering value that puts you fully in control of your OS, application infrastructure and application.


Securely store files in the cloud and access them anywhere via a virtual network drive on your desktop or on the web. In order to optimize the performance, security and scalability of your infrastructure, it is critical to have the right compute platform supporting each element of your hosted solution. Rackspace offers a complete portfolio of compute platforms as well as Hybrid Hosting to make them all work together seamlessly. Hybrid Hosting means you get the best of both worlds: Dedicated Hosting for mission-critical applications, plus the flexibility and fast provisioning delivered by the Cloud. Whether you require Dedicated Servers and Cloud Servers operating independently for different workloads, or a seamlessly integrated architecture for bursting extra compute cycles, Rackspace Hybrid Hosting allows you to mix and match compute platforms to best suit your needs. Make no mistake, and you would find them to be the most cost-effective solution AND the best supported cloud offer. You can find latest information, news, tips, deals and promo codes regarding the hosting industry and hosting companies.

I pick the SUV version on Rackspace’s Cloud offering and purchase the 8 GB, SSD, 8 CPU Machine. My other friends don’t carpool like they had planned and everyone bought a new SUV so we each drive our own.
Imagine how happy the customer would be receiving a phone call from his trusted MSP advisor asking them if they’d like to accept a price cut based on lower allocation because they were able to analyze they didn’t need it?
If 5% of 1 CPU ready equals 1000milliseconds of delay on my CPU scheduler, how many less performance tickets requiring support staff response could I avoid? Eric discovered that by leveraging IT algorithms based on the principles of supply and demand, software can solve some of the biggest challenges in infrastructure and cloud management today.

Recently we have used our new Linux benchmark suite to test new systems from both Amazon and Rackspace as well as a few non-cloud servers such as the Intel Atom S1260 platform. We started five Next Generation Dallas instances and five Next Generation Chicago instances and got the same configuration. The overall test result set that the heatmap is generated from utilizes a wide array of hardware and cloud instance types. There are two main versions, one that tests single CPU performance on that tests multiple CPU performance.
First, the Rackspace cloud instances often have very similar performance due to the same underlying architecture. Likewise we are seeing the increments continue at the 15GB instance type and 30GB instance type. Traditionally ray tracing is an application where scaling is shown very well and that proves true here. It is also one where we saw issues last time with the Phoronix Test Suite and running on ARM CPUs. In fact, it is arguably becoming even more popular these days so we decided to include a pyBench benchmark in the results.

Cloud Files integration with Akamai’s CDN allows you to serve your content globally, giving you high-speed delivery of content to your site and faster page loads for your site visitors. The growth of Cloud Files, now one of the largest storage platforms in the cloud, is giving us the economies of scale that allow us to reduce costs and pass savings to you. At present, Cloud Files is based on the OpenStack Object Storage Essex release which includes code contributions from a global community of developers, software companies, hardware vendors and service providers. Also, remember you can always contact Support to send us your data by mail using Bulk Import. The danger in using these packages, from a security standpoint, is that they are so common as to make a large target for malware writers.
As a result of these infrastructure improvements, our ability to provide support will be limited until maintenance completion. And then you can click the saved session to start the pre-configured SSH session, thus don’t have to enter the host name and port every time you need to connect.
I can’t do all the content myself so I constantly use article writing services to get the jobs done. Section the article well and title those sections well so readers can find something very very quickly. Your IT organization manages your applications and maintains full control over the operating system and application infrastructure.
In addition, Rackspace  Hosting also delivers a number of key services designed to keep your applications secure, stable and responsive to your changing business needs.


There is no learning curve; it works just like any other drive, drag and drop, copy and delete. No exceptions!” You then begin to dream about puppies and kittens when all of a sudden your alarm goes off and you’re snapped back into reality. If I can use my supply (my driveways) to better meet the demand and usage of my workloads (cars), then I can redefine my trade-off between revenue and infrastructure cost. Eric joined VMTurbo in 2011 where he quickly developed a passion for the technology and was named Sales Engineer of the Year for both 2013 and 2014, in addition being recognized for the board leadership award and founder’s award. They’ll help you design the right combination of compute, network, storage, and traffic management services - so your environment meets your current needs, but also has the flexibility to grow with your business.

The results have shown both significant scaling as well as some differences between the two providers. The green shading on the 8GB to 30GB Rackspace instances shows that these instances are performing nearer to the top of the pack. The sample instance types above show the CPU scaling we would expect from scaling the Rackspace Cloud instance size. This makes sense as the Rackspace cloud instance documentation clearly shows where extra compute resources are added.
The goal of STH is simply to help users find some information about basic server building blocks. The php memory value is how much memory your application is requiring to load each webpage.
With pay-as-you-grow pricing, you only pay for the amount of storage and outgoing bandwidth you actually use. If you have any questions regarding Cloud Files, don’t hesitate to give me or my sales team a call. Combine this with their support for third-party add-ons and the rapid speed of development, and it’s easy to see how vulnerabilities can creep in. We do not expect this update to result in any downtime to the Rackspace Cloud production environment, only to the management tools and API. Like, after you double click the PuTTY shortcut in Windows, it will automatically connect to the remote server AND supply the SSH user name as well as password so you don’t have to.
For example, an article that yells and calls names (not necessarily so, just making a point).
People attentions are very very short on the web and they generally hate large blocks of tedious texts. But if you can do the writing the way I described above, I’d still pay you a solid $xx even if you only wrote 300 words.
Easily set up multiple drives that can be accessed from any desktop or on-the-go through a secure web interface. Store an unlimited number of files with an included 10GB per user and additional storage available on demand. Files are updated as changes are made and are synced online as well as on teammate’s computers. The reality where you actually have to go to work and weigh the trade-offs of VM allocation in a shared model vs. But when we really inspect this equation, we realize that’s it’s not about simple abstraction.
He now serves as a Manager of Sales Engineering for the Western Sales Region, where he helps organizations unlock the full value of virtualization through the implementation of software-defined control.
They'll also provide valuable expertise in the things you struggle with the most, including architecting for scale, monitoring, responding to alerts, and running your cloud environment's operations and administration. Today, in the spirit of rapidly publishing the data we are collecting, we are releasing benchmark results on all of the Rackspace cloud instance types. We are including a few smaller Amazon AWS EC2 instances as a point of comparison as well as the Intel Atom S1260 Centerton SoC dedicated server. For each cloud instance type test we are using five instances (with the same underlying hardware) and five iterations each. I used to buy articles by words but later gave up on this approach because I found writers who charge by words isn’t quite good. It’s rather long with tedious paragraphs and little section heading (even if there were, they were too short and non-informative).
Though it’s very much painful for me to manage the vps box myself, it’s a great learning experience after all and I did learn a lot!
Go offline and keep working; the files will update as soon as an Internet connection is established.
It’s about the greatest yield to our entire virtualized eco system: The one that allows us to ensure application performance while simultaneously increasing infrastructure efficiency.
These benchmarks scale from the small 512MB RAM instance to the 30GB of RAM instance which is a fairly wide performance spectrum.
The sample size is not huge, but large enough that we are seeing variations in the Rackspace cloud (and Amazon cloud for that matter.) The important thing to remember here is that if one wants very consistent performance dedicated hardware will be a bit better.
Needless to say, oftentimes these results are hard to reproduce unless one is trying to squeeze every ounce of performance from a machine they are optimizing for. The important thing to note here is that the underlying architecture of any cloud instance can have a significant impact on scaling. They are eager to help those who need tips to set up and harden their boxes against security breaches.
