How SimpliVity Gave Me Back My Weekend

At GreenPages, we have a well outfitted lab environment that is used for customer facing demos and as a sandbox for our technical team to learn/experiment/test various solutions in the market.  We’ve been in the process of refreshing the lab for a couple of months but have kept a skeleton environment up and running for simple administrative remote access.  As part of the refresh, we had been cleaning up old VMs, systems, storage, etc. to reduce our footprint, and as part of the cleanup we moved several management VMs from an aging HP blade environment over to a small 2+1 SimpliVity OmniStack environment.  I really didn’t think much about it at the time as I just needed a place to put these VMs that had no tie to older systems, which were being decommissioned. Also, the OmniStack made sense because it had plenty of capacity and performance self-contained, thus freeing up any reliance on other external storage and older compute environments.

I just recently came back from a West coast trip. While I was there, I needed to re-configure something so that a colleague could do some other configuration work.  I brought up my RDP client to login to the jump box terminal server we use to administer the lab, and I got an error that said my profile wouldn’t load.  So, I VPN in to check out the VM, logged in as the local administrator, and quickly discovered the box had been pwned with ransomware and a good majority of the data files (my profile included) were encrypted.  After saying a few choice words to myself I investigated and determined an old lab account with a less than secure password had been used to access the system.   I got the account disabled and started thinking to myself how long it’s going to take me to either attempt to ‘clean’ the box and get the files decrypted (assuming I could even find a tool to do it) or to just trash and rebuild the box.  I figured that was going to take up most of my weekend but then the thought crossed my mind that we had moved all of the management VMs over to the SimpliVity boxes.

For those who may not be aware, SimpliVity’s core value proposition is all around data protection via integrated backup, replication, and DR capabilities.  I knew we had not configured any specific protection policies for those management VMs, we had simply dumped them into newly created resource pool, but I figured it was worth a look.  I logged into the vSphere client and took a look at the SimpliVity plugin for that terminal server VM and, low and behold, it had been backed up and replicated on a regular basis from the moment it was put into the environment.  From there, I simply went back a couple of days in the snap-in, right click, restore VM.  Within about half a second, the VM had been restored, and I powered it up and within another five minutes, I was logging into it via my RDP session from the West coast.  Bottom line, SimpliVity took a four to six hour process and transformed it into something that takes less than six minutes.  Therefore, I suggest you check it out.  Thank you SimpliVity, for being kind enough to donate some gear to our lab and for giving me some family time back this weekend!

Guest Post: How to Minimize the Damage Done by Ransomware

Below is a guest post from Geoff Fancher, Vice President, Americas Channels at SimpliVity Corporation

Have you ever woken up in the middle of the night, sweating profusely, scared half to death, and terrified that your data center was infected with ransomware? If so, you’ve had an IT nightmare. Just be thankful it was all just a dream and your data isn’t lost.

Though IT nightmares come in all forms, one thing all IT pros fear nowadays is ransomware. That’s because ransomware is becoming increasingly commonplace and is evolving to become even more vicious and hard to stop once it has entered an IT environment. The cost to business productivity can be crippling, and the data loss that can occur can set a company back for days.

According to Ponemon Institute, the average cost of IT downtime is $7900 per minute. Per minute! The reason recovering from ransomware attacks can be so costly is that backing up from restores can take a long time, typically measured in hours or days depending on where and how backups were stored. Also, depending on when the most recent backup took place, a lot of data could be lost once the backup is recovered.

With the cost of downtime due to ransomware being so high because quick restores aren’t an option, many organizations are choosing to pay the ransom to get their data back. The most notable example comes from Hollywood Presbyterian Medical Center. The hackers infected the hospital’s computer systems, shutting down all communication between the systems, and demanded $17,000 to unlock them. The hospital, being in an a high-pressure situation without the correct resources to be able to quickly shut down its systems and restore from a recent backup, was forced to pay the ransom to receive the decryption key and get back online.

The fundamental piece, then, to avoiding paying the ransom demanded by cyber criminals is to have a disaster recovery plan in place. You should know what to do if a ransomware attack happens. As the old adage goes, “Hope for the best. Prepare for the worst.” That’s the attitude to take and the way to do it is to have a plan.

One company that instituted a solid disaster recovery plan just in the nick of time was an enterprise manufacturing company based in the Netherlands. The company was infected with ransomware while its IT partner was in the process of migrating VMs to a new hyperconverged infrastructure environment that had built-in data protection. Most of the infected folders were already on the new solution, which was lucky because they were able to use the solution’s backup to restore within fifteen minutes, when just a day before, on the previous infrastructure, it would have taken about three hours to restore to the most recent backup. The partner was also performing hourly backups on the new solution, so they lost less than an hour’s worth of data during the restore. Before deploying hyperconverged infrastructure, the partner was backing up to tape every 12 hours, so they saved the company about 11 hours of data loss on the new hyperconverged solution. What a difference a day makes.

For a disaster recovery plan to be successful, the IT team needs to define recovery time objectives (RTOs) – how long it takes to restore the backup – and recovery point objectives (RPOs) – the nearest backup they can restore from. Basically, businesses have to ask themselves two questions: How long can the business shut down while waiting for the restore to take place? And, how many hours of business-critical data can the company afford to lose? There are data protection plans for every size of company and for every budget. The first step to a data protection plan is defining the organization’s requirements.

Hyperconverged infrastructure, for example, can dramatically cut down the hours it takes for businesses to recover from IT downtime. By making data efficient from the start of its lifecycle, businesses are able to quickly recover from a previous backup.

With SimpliVity hyperconverged infrastructure, companies are able to backup quickly and efficiently with minimal data loss because SimpliVity’s solution is designed to meet even the most stringent RTOs and RPOs to ensure businesses functions aren’t interrupted for long in case of a disaster or ransomware attack.

Deciding between private and public cloud

cloud computing machine learning autonomousInnovation and technological agility is now at the heart of an organization’s ability to compete.  Companies that rapidly onboard new products and delivery models gain competitive advantage, not by eliminating the risk of business unknowns, but by learning quickly, and fine-tuning based on the experience gathered.

Yet traditional IT infrastructure models hamper an organizations’ ability to deliver the innovation and agility they need to compete. Enter the cloud.

Cloud-based infrastructure is an appealing prospect to address the IT business agility gap, characterized by the following:

  1. Self-service provisioning. Aimed at reducing the time to solution delivery, cloud allows users to choose and deploy resources from a defined menu of options.
  2. Elasticity to match demand.  Pay for what you use, when you use it, and with flexible capacity.
  3. Service-driven business model.  Transparent support, billing, provisioning, etc., allows consumers to focus on the workloads rather than service delivery.

There are many benefits to this approach – often times, cloud or “infrastructure as a service” providers allow users to pay for only what they consume, when they consume it, as well as fast, flexible infrastructure deployment, and low risks related to trial and error for new solutions.

Public cloud or private cloud – which is the right option?

A cloud model can exist either on-premises, as a private cloud, or via public cloud providers.

In fact, the most common model is a mix of private and public clouds.  According to a study published in the RightScale 2015 State of the Cloud Report, enterprises are increasingly adopting a portfolio of clouds, with 82 percent reporting a multi-cloud strategy as compared to 74 percent in 2014.

With that in mind, each workload you deploy (e.g. tier-1 apps, test/dev, etc.) needs to be evaluated to see if it should stay on-premises or be moved offsite.

So what are the tradeoffs to consider when deciding between private and public cloud?  First, let’s take a look at the considerations for keeping data on-premises.

  1. Predictable performance.  When consistent performance is needed to support key business applications, on-premises IT can deliver performance and reliability within tight tolerances.
  2. Data privacy.  It’s certainly possible to lose data from a private environment, but for the most part, on-premises IT is seen as a better choice for controlling highly confidential data.
  3. Governance and control.  The private cloud can be built to guarantee compliance – country restrictions, chain of custody support, or security clearance issues.

Despite these tradeoffs, there are instances in which a public cloud model is ideal, particularly cloud bursting, where an organization experiences temporary demand spikes (seasonal influxes).  The public cloud can also offer an affordable alternative to disaster recovery and backup/archiving.

Is your “private cloud” really a cloud at all?

There are many examples of the same old legacy IT dressed up with a thin veneer of cloud paint.  The fact is, traditional IT’s complexity and inefficiency makes it unsuitable to deliver a true private cloud.

Today, hyperconverged infrastructure is one of the fastest growing segments in the $107B IT infrastructure market, in part because of its ability to enable organizations to deliver a cloud-operating model with on-premises infrastructure.

Hyperconvergence surpasses the traditional IT model by incorporating IT infrastructure and services below the hypervisor onto commodity x86 “building blocks”.  For example, SimpliVity hyperconverged infrastructure is designed to work with any hypervi­sor on any industry-standard x86 server platform. The combined solution provides a single, shared resource pool across the entire IT stack, including built-in data efficiency and data protection, eliminating point products and inefficient siloed IT architectures.

Some of the key characteristics of this approach are:

  • Single vendor for deploying and supporting infrastructure.  Traditional IT requires users to integrate more than a dozen disparate components just to support their virtualized workloads.  This causes slow deployments, finger pointing, performance bottlenecks, and limits how it can be reused for changing workloads. Alternatively, hyperconvergence is architected as a single atomic building block, ready to be deployed when the customer unpacks the solution.
  • The ability to start small and scale out without penalty.  Hyperconvergence eliminates the need for resource allocation guesswork.  Simply start with the resources needed now, then add more, repurpose, or shut down resources with demand—all with minimal effort and cost, and no performance degradation.
  • Designed for self-service provisioning. Hyperconvergence offers the ability to create policies, provision resources, and move workloads, all at the VM-level, without worrying about the underlying physical infrastructure.  Because they are software defined, hyperconverged solutions can also integrate with orchestration and automation tools like VMware vRealize Automation and Cisco UCS Director.
  • Economics of public cloud. By converging all IT infrastructure components below the hypervisor and reducing operating expenses through simplified, VM-centric management, hyperconverged offerings deliver a cost model that closely rivals the public cloud. SimpliVity, for example, is able to deliver a cost-per-VM that is comparable to AWS, including associated operating expenses and labour costs.

It’s clear that the cloud presents a compelling vision of improved IT infrastructure, offering the agility required to support innovation, experimentation and competitive advantage.  For many enterprises, public cloud models are non-starters due to the regulatory, security, performance, and control drawbacks, for others, the public cloud or infrastructure as a service is an ideal way to quickly increase resources.

Hyperconvergence is also helping enterprises increase their business agility by offering all the cloud benefits, without added risks or uncertainty. Today technology underpins competitive advantage and organizations must choose what works best for their business and their applications, making an approach combining public cloud and private cloud built on hyperconverged infrastructure an even more viable solution.
