Fixing private cloud computing performance issues

Much has been made of how businesses can enhance their IT performance by migrating to a private cloud. But more and more enterprise level organizations are realizing that the promise of the cloud isn’t always realized after implementation. This is partly because much of the marketing around the private cloud talks about potential savings and increases in performance that are based on best case scenarios.  The actual “on-the-ground” numbers vary quite a bit.  The good news is that there are a number of steps most organizations can take optimize the performance of the private cloud itself. Here are a few to get you started:

  • Negotiate your SLAs with care
  • Smart cloud users always monitor performance
  • Time to upgrade your WAN?
  • Take advantage of automation

Virtualisation’s complex licensing is a ‘ticking timebomb’, claims study

Software licensing under virtualisation remains a grey area and many organisations are likely to have a significant shortfall in their software licensing compliance making them particularly vulnerable in a software audit, warned a licensing management service provider, License Dashboard.

A study it conducted among UK organisations in December 2012 revealed that nearly all respondents (97%) had virtualised their servers and more than half (58%) said they used dynamic provisioning – a flexible approach where virtual machines (VMs) are deployed from a centralised administrative console by any central IT administrator.

Using dynamic provisioning (such as VMware’s Distributed Resources Scheduler – DRS) has the potential to increase an organisation’s server licensing requirements by up to 500% at the click of a button, warned License Dashboard.

Don’t Get Catfished: Bridge the Physical and Virtual

I recently caught an episode of a documentary series my kids were watching on MTV, called “Catfish.” In the show, people who were in online-only relationships tried to find out if the person they’d been chatting with was actually who she/he claimed to be. It won’t come as a surprise to anyone that they usually weren’t. Think the Manti Te’o hoax.

As someone in the IT world, I began to think about other ways in which the virtual and physical IT worlds don’t always line up. As we turn to virtualization and the Cloud, we often struggle to integrate physical devices to support virtual systems. And just like in “Catfish,” the reality is often not what we’d hoped.

This is particularly true for SANs. We’re going from a one server, one application world to one in which many systems all access the same storage. The performance of traditional SANs has often been inadequate, and the difference between locally attached and virtually provisioned storage can be very noticeable.

Why is that? What aspects of traditional SANs are in conflict with virtual infrastructures? The fundamental problem is a lack of what I call “VM awareness.”

  • Physical vs. Virtual System Performance (… Real People vs. Facebook Profiles)
  • Bridging the Physical and Virtual (… Know Who You’re Talking To)
  • Merging the Physical and Virtual (… Reality Check)
  1. First, your SAN needs to be able to handle a large number of IOPS.
  2. Second, your storage needs to be able to prioritize data
  3. Third, the system needs to deduplicate data blocks.
  4. Lastly, storage management needs to integrate with VM management.

How to Build a Private Cloud: Advice from the Experts

For many enterprises, the safest on-ramp to cloud computing is to build a private cloud. Private clouds don’t have as many security, compliance and data-ownership challenges as public ones, but they are not risk free.

Legacy environments, cost overruns and application performance can all undermine your private cloud initiatives. That doesn’t mean you should rethink the decision to build a private cloud, but it does mean you need to carefully think through the challenges—and be realistic about potential benefits.

If you understand the challenges you’ll face and plan ahead to overcome them, building a private cloud will put you on the road to a streamlined, efficient and flexible IT infrastructure.

To help you succeed when it comes time to build your own private cloud, here are five tips from private cloud experts:

  1. Avoid Forklift Upgrades.
  2. Determine How You Will Measure Success.
  3. Plan for the Future Growth and Changing Makeup of Your Organization.
  4. Strive to Meet—Or Beat—the Performance of Your Previous Architecture.
  5. Figure Out Who Will Pay for What.

The Debate Over Public Vs Private Cloud Computing

Whenever discussing cloud computing systems, уου wіll οftеn hear mentions mаdе tο private аnd public clouds, along wіth debates over thе comparative advantages οf each. Tο thе cloud technology novice, thіѕ entire private cloud vs. public cloud dispute саn sometimes sound lіkе іt іѕ being debated іn a foreign language. Thе following article identifies thе differences between public аnd private cloud computing, аnd ехрlаіnѕ thеіr іmрοrtаnt differences іn common terminology.

Defining Private Cloud Technology


Tο рυt іt simply, private cloud technology іѕ a type οf architecture thаt іѕ set up fοr a lone client (generally a large business). Wіth thіѕ kind οf arrangement, thе provider controls thе framework bυt enables thе client tο control data storage, аѕ well аѕ thе manner іn whісh іt’s transferred. It’s thіѕ higher degree οf customer control thаt mаkеѕ private cloud technology рοрυlаr wіth clients whο happen tο bе particularly concerned аbουt security.

Benefits οf Private Cloud Solutions

Bу providing thе customer additional control, thе private cloud іѕ аblе tο eliminate many prospective security concerns. Bу shifting іtѕ existing IT system tο thе cloud, thе client wіll bе аblе tο еnјοу thе conveniences οf scalability, flexibility аnd better productivity, bυt hаѕ thе ability tο dο ѕο without having tο sacrifice thе accountability fοr data security thаt mау bе related tο public cloud computing systems.

Thе Disadvantages tο Private Cloud Technology

Possibly thе bіggеѕt problem wіth private cloud services іѕ thаt οftеn thе еnd user mυѕt рυrсhаѕе computer hardware, configure іt, аnd bе аblе tο continue tο maintain іt. Whіlе thе public cloud consumer саn essentially bυу a cheap, ready-frοm-thе-box system thаt саn bе employed immediately, thе private user hаѕ tο commit substantial capital up front tο gеt a system thаt wіll bе hosted internally, аnd thеn continue tο deal wіth іtѕ management going forward. Sο аѕ tο benefit frοm thе increased security thаt comes wіth a private solution, thіѕ іѕ thе required trade-οff.

Introducing Private Cloud – The Pitfalls to Avoid!

The business world is abuzz with discussion on the best practices of adopting private cloud. The preference for private over public is mainly because of service-level, data security and portability issues that surround a third-party cloud computing system. Companies that want to retain complete control over their data on a cloud environment are mostly inclined to adopt private cloud set-up. Unfortunately we have experienced that private cloud computing projects have a higher rate of failure. It can be attributed to the following conditions:

  1. Insufficient Planning:
  2. Vision:
  3. Collaboration:
  4. Skewed Expectations:
  5. Preparing the Ground:
  6. The Testing:
  7. Strategic consolidation:

Understanding The Cloud Computing Infrastructure

As a long time advocate of cloud computing, I already know most of the technology and terms surrounding cloud computing and if someone mentions a new application or feature I might be able to gleam how it works based on the technologies used. This is not necessarily true for most people even if they have been in the IT industry for a long time. That is why I write “simple” articles that the less informed might be able to grasp easily. But to get a real understanding of something, you need to get an understanding of its internal structure, understand how it works and not just what it does. If someone tells you that an airplane flies because of engines and wings, it will still seem like magic because you are not really informed on the how. Same as cloud computing, for many it simply provides them with that service that they take for granted without really knowing how it is done. And to understand it better, we must understand the underlying infrastructure of cloud computing.

To put it simply, the infrastructure or how all the hardware technology and other elements come together cloud computing is very similar to that of traditional network computing. You have your servers that contain the CPUs, RAM, and other processing elements, and then you have your various storage devices like NAS and RAID-style setups. Of course, to round out the bunch you have your networking hardware, the routers, switches, modems, repeaters, and any and all combinations of networking hardware technology. If you look at the list I just mentioned, it is obvious that the hardware used for cloud computing has been existing, but why hasn’t cloud computing existed as long?
