Cloud Resiliency: Overview, Benefits & Steps for Implementation

/in

business resilienceWhat is Resiliency in Cloud Computing?

In today’s rapidly evolving digital landscape, where businesses increasingly rely on cloud computing for their critical operations, the need to ensure uninterrupted services and data availability has become paramount. This is where “Cloud Resiliency” steps in as a fundamental aspect of modern IT strategy.

Cloud resiliency refers to the ability of a cloud-based system or infrastructure to withstand and recover from unexpected disruptions, whether they arise from hardware failures, software glitches, cyberattacks, natural disasters, or any other unforeseen events. It involves designing and implementing a robust framework that can promptly detect issues, gracefully handle failures, and swiftly restore normal operations without significant downtime.

The unexpected will happen. It is inevitable. Sometimes the unexpected is a good thing. In technology, the unexpected is usually bad.  It may be small … or big … or catastrophic.

Part of our role as IT professionals is to expect and prepare for the unexpected. We backup data so that we can restore files that are accidentally deleted, overwritten, or damaged.  We backup systems so that we can recover them in case of hardware or software failures. Many business designs and implement disaster recovery plans. These plans provide the means for companies to recover from larger incidents, ranging from burst pipes and building fires to blizzards and hurricanes.

In recent years, the focus has been on “Business Continuity” planning. Business continuity intends to prevent disruption to operations, even in the face of larger incidents or disasters. While great in concept, most small and mid-size enterprises cannot afford to fully duplicate systems in redundant data centers and provide alternate work sites for employees.

Cloud Resiliency in Business

Business Resiliency is based on the objective of enabling a business to continue (or rapidly resume) operations with some accommodations.  In other words, you may not be running 100%, but you will be running soon enough and well enough, given the situation. Resiliency is about bending without breaking.

Consider Hurricane Sandy which devastated parts of the US Eastern Seaboard.  Many businesses were physically destroyed by the flooding. Many others were shut down by the indirect effects of the flooding as some areas along the coast lost critical infrastructure — including water and sewer. Businesses left physically intact but without power for days considered themselves lucky as some areas waited months for reconstruction.

Consider the ice storms and blizzards throughout the Northeast US in recent years.  For many businesses, the only disruption was loss of power.  And while in many of the storms, outages where generally localized, some businesses went without power for as long as three weeks.

The same holds true for businesses in “tornado alley” in the Midwest. A tornado may leave your business unscathed, but it may take days or weeks for power and water to be restored.

In each of these scenarios, backup/restore/recovery is not enough to get the business back up and running. And, again, most small and mid-size businesses cannot afford to maintain disaster recovery systems and sites.

Benefits of Cloud Resiliency

Cloud resiliency offers a wide range of benefits to businesses and organizations that rely on managed cloud-based services and infrastructures. These advantages contribute to the overall stability, availability, and security of digital assets, ensuring uninterrupted operations and safeguarding against potential disruptions. Here are some key benefits of cloud resiliency:

  1. High Availability: Cloud resiliency ensures that critical applications and services remain available even in the face of hardware failures, software glitches, or other unforeseen events. Redundancy and failover mechanisms enable seamless transitions to backup systems, minimizing downtime and maintaining continuous access for users.
  2. Disaster Recovery: Resilient cloud architectures provide robust disaster recovery capabilities. Regular data backups, real-time data replication, and well-defined recovery processes allow businesses to recover quickly from data loss, cyberattacks, or natural disasters, minimizing potential data and revenue loss.
  3. Reduced Downtime: With cloud resiliency in place, businesses experience reduced downtime during system failures or maintenance activities. Quick detection and automatic recovery mechanisms help prevent prolonged service interruptions, enhancing productivity and customer satisfaction.
  4. Business Continuity: Cloud resiliency ensures business continuity by allowing organizations to maintain essential operations even during disruptive events. Critical business functions can continue operating, meeting customer commitments and minimizing financial losses.
  5. Cost Efficiency: While implementing cloud resiliency may involve upfront investments, it ultimately proves cost-effective in the long run. The ability to prevent extended downtime or data loss reduces potential revenue losses and protects a company’s reputation.
  6. Scalability: Resilient cloud infrastructures are designed to scale dynamically to meet changing demands. As businesses grow or experience fluctuating workloads, the cloud resiliency framework can seamlessly adapt, ensuring optimal performance and resource utilization.
  7. Enhanced Security: Cloud resiliency often goes hand-in-hand with robust security measures. Proactive identification and mitigation of vulnerabilities help protect against cyber threats and unauthorized access, safeguarding sensitive data and intellectual property.
  8. Improved Customer Trust: Reliability and continuous availability of services build trust with customers and partners. Knowing that their data and operations are in safe hands, clients are more likely to choose a resilient cloud service provider, giving businesses a competitive advantage.
  9. Regulatory Compliance: Resilient cloud architectures often adhere to industry-specific regulations and compliance requirements. Meeting these standards is critical for businesses operating in regulated sectors, ensuring legal adherence and avoiding potential penalties.
  10. Faster Recovery Times: In the event of a disruption or disaster, cloud resiliency enables faster recovery times compared to traditional on-premises solutions. Automated recovery processes and failover capabilities reduce the time required to restore services and operations.
  11. Geographical Redundancy: Resilient cloud infrastructures can be distributed across multiple data centers in different geographic locations. This geographical redundancy further enhances data protection and disaster recovery capabilities, minimizing the impact of regional outages or natural disasters.

Cloud Resiliency Requirements

Achieving cloud resiliency involves careful planning, robust architecture design, and the implementation of various measures to ensure the system can withstand and recover from unexpected disruptions.

Most businesses can afford to move IT systems into cloud computing and hosted solutions.  And in doing so, businesses can affordably build resiliency.

With all of these disasters, you did not have to travel too far inland to be out of the damage zone.  Businesses with on-premise equipment had to purchase and wait for delivery of replacements, rebuild their systems, and (hopefully) recover their data from their off-site backups. Certainly doable, but costly and time consuming.  It can take 2 to 4 days just to get the equipment in place and ready to restore.

Businesses in the cloud faced a different scenario and outcome. Moving to an area with power and Internet, businesses running in the cloud were up and running in hours (some in minutes) and some were never “down” at all.

In IT, Every Season is Hurricane Season

/in ,

Hurricane
June 1st is the official start of Hurricane Season for North America. Every year, we hear predictions for the number of storms and the number of major storms expected to hit landfall here in the U.S. And yet, every year we seem to over-prepare for storms that never become a major problem and under-prepare for storms that become truly dangerous.

Such is the life for IT Hurricanes

Unlike physical hurricanes that can cause power and system outages, IT “Hurricanes” are climate changes that impact your business, and its IT needs and priorities.

As with physical hurricanes, IT Hurricanes often start out as smaller disturbances that are seen and identified well in advance. Some lose their energy and dissipate, some get carried off by changing currents, and some turn into storms.

Even with the advanced notification, dare I say warning, we often struggle to assess the size, scope, and impact of IT Hurricanes until just before they are about to hit. All too often, IT Hurricanes gain unexpected power and momentum as they approach landfall. Decisions on how best to prepare are often made too late for effective planning and execution, leaving IT staff scrambling to mitigate the impact and repair the damage.

For many businesses, our infrastructure and systems are not well-prepared to withstand IT Hurricanes. They are too rigid to adapt to changing winds and tides, too difficult to move to a safer place, and/or unable to withstand the tidal surge of change forced upon us.

Look to the Cloud for a Better Way

Rather than just focusing on improving our warning time and how well we can predict the direction, size, and strength of IT Hurricanes, we should create IT infrastructure and systems that can adapt to changing conditions more easily, with less time required.

Moving to cloud solutions can …

  • Simplify your IT infrastructure — your network and systems — making it easier and less expensive to adapt to changing currents
  • Reduce the amount of capital captured in physical assets with sunken costs that resist change
  • Let you raise or lower you capacity and utilization as needed to ebb and flow with the tide of your business
  • Add, or modernize, applications and systems without having to airlift in a solution
  • Improve mobility, so your team members are never displaced by geography or device
  • Provide a platform, that lets you create an IT ecosystem for your business focused on the future and not the past

While cloud computing cannot prevent IT Hurricanes, cloud solutions can help mitigate the impact and make it easier for you and your business to adapt and respond. After all, staying ahead of the storm is better than having to pick up the pieces.

Using the Google Apps for Work ecosystem, our CumuluSuite packages provide cloud computing platforms that are easily customized to keep you out of the storm.  Contact us to learn more.

 

Changing the Focus on Backup Protection

/in ,

Recovery-Point-Objective-RPO
As we’ve stated before, “Backup is easy; Recovery is hard”.  Every business should, at this point, understand the risks of poor data backup and protection. The risks come from the types and amount of data that is lost and, if it can be recovered, how long that recovery takes. And remember, recovery often takes more effort than simply restoring files from a backup set.

Perspective = Priority

When looking at how well your backup system is protecting your business, two factors should be top of mind:

RTO: Recovery Time Objectives — How long will it take to return to normal operations. RTO is not just the time it takes to load your data back onto your systems, RTO includes the time it takes to repair and recreate damaged information and data created or modified since the last backup.

RPO: Restore Point Objectives — Your RPO determines how much data you are willing to lose, or can afford to lose. Most small and mid-size businesses backup daily. On average, a system failure will result in half a day of lost data. For an office worker editing a report, this is traumatic and inconvenient. For a manufacturer or retail business, half a day can represent hundreds or even thousands of orders and financial transactions.

As always, quicker RTOs and smaller RPOs come with trade-offs.  Recovery methods like image snapshots, for example, can provide rapid RTOs and small RPOs. In exchange, you are likely losing granularity — the ability to recovery individual files.

Understand the reasons  you are protecting your data.  Protection from system failure, in which you need to recovery a full server, lends itself to imaging and other snapshot methods.  Recovery of files or data lost to program error, malware, or user activity, needs a solution with granularity.

Start with an understanding of the type of protection you need and your RPOs and RTOs.  From there, you can pick the solutions (yes, you may want or need more than one method) for recovering data and your business.

We offer  a range data protection solutions, with a range of products, for on-premise and cloud-based data. Contact us for a free assessment of which type of solution is best for you.

When FiOS becomes “Frequent Interruption of Service”

/in


We love the cloud.  We work and live in the cloud. So, when our Verizon FiOS service became unreliable, we had a plan.

The upside of cloud services is that they are available from anywhere you have Internet service.  The down-side is that downtime means disruption.

We Have Options

Redundancy is the most common option considered to avoid Internet service disruptions. In our location, we could add a Charter business connection along side our Verizon FiOS service, and reconfigure our Cisco ASA 5505 to load balance and manage fail-overs. The upside: we avoid outages and service quality issues; the downside is the setup cost and recurring fees.

For now, we have taken a tactical approach. Our service issues are frequent, but short in duration (the side effect of DDOS attacks elsewhere on the network).  When quality drops or the service is down completely, we switch to our MiFi and smartphone HotSpots for Internet access.  By disabling WiFi and relying on the 4G LTE service, we run a softphone client on our iPhones and Android phones, providing full telephony capability and coverage.

While we may deploy a redundant carrier in the future, the flexibility of our cloud-based services and our cellular based Internet access are sufficient in the short term.  Having options, and being able to work, is all part of our Business Continuity planning.

 

Picking a Backup Solution is Missing the Point!

/in ,

Data Protection
A 2013 study by The 2112 Group titled “”2013 State of Cloud Backup” found that small and mid-size interest in robust backup solutions more than triples after a significant data loss event, only 54% of SMBs felt that improved data recovery, business continuity, and IT reliability were sufficient motivators to deploy a new or improved solution.

Our perspective, is that focusing on backup misses the point entirely!

As we have blogged in the past: backup is easy; recovery is hard.  More accurately, the ability to recover and restore defines the value proposition.  Everything else about “backup” solutions — including the technology and methods — is irrelevant until you define the value of recovery and restore.

Stop thinking about Backup!  Instead, think about:

Continuity:  The ability for you company to continue to operate at an appropriately effective level during events that disrupt normal operations.   For some businesses, this means zero downtime.  For others, answering the phones and access to email may be sufficient for hours or days, or as an interim state until line of business systems come back online.  Still other businesses may need all systems up and running with 1 or 2 business days.

Recovery:  The ability to gain access to data and systems that became unavailable due to damage or failures.  Whether your disk array fails, a pipe bursts above your servers, or a virus eats through your files, recovery requires repair or replacement before systems and data can be restored.

Restore:  The ability to retrieve a prior version of data or a system.  Most restores are a result of user action or minor system issues.  How far back you need to go and the availability of past versions defines how long it will take to both retrieve the information and for the user to replace lost work, if any.  For some, a daily version meets the need.  For others, going back a day means resource-consuming rework so multiple versions each day are appropriate.

Focus on a building a Data Protection Solution and your required “Return to Operation” (RTO) time.  Remember that different parts of your business, different systems, may have different RTO requirements.

  • Assess your continuity, recovery, and restore needs and priorities
  • Understand the likely and not-so-likely risks to your systems and your business and create a “use case”.
  • Looking at each use case:
    • Identify changes to your IT infrastructure that could mitigate risk
    • Identify the type of solution that can provide the needed continuity, recovery, and restore services
  • Collate the use cases and solution types as your requirements

With requirements in hand, evaluating data protection solutions, technologies, and services becomes a manageable process.  Keep in mind, the data protection solution may include a mix of backup/restore, backup/recovery, archiving, disaster recovery, and other components.

 

Tuesday Take Away: 8 Ways that Clouds Beat Blizzards

/in

Once again, the team and I at Cumulus Global found ourselves working from our homes, pizza shops, libraries, and coffee shops.  An unusual and record-breaking October Nor’easter dumped about a foot of very heavy and wet snow on us, snapping power poles and trees like, well, twigs.  In our area of the state, most towns reported between 60% and 100% of residences and businesses without power.  Starting on Saturday evening, many will be without power until late Thursday or Friday.

Businesses tied to their physical offices, again, are learning the hard way how Cloud Computing can help keep things running when life throws the unexpected your way.

1) Message Continuity

If you run MS Exchange, Google Message Continuity not only provides you with bullet-proof spooling if your server or Internet link are down, you get Gmail’s web interface and the ability to send and receive emails.  And while most email contingency services dump all activity in your spool to your inbox (including sent message), GMC actually syncs your sent and saved messages, preserving your folders and your sanity.

2) Cloud Storage Mirror

Different than backing up for restores or recovery, synchronizing or mirroring local and network data to a cloud service gives you the ability to access and use your documents, usually through a web interface, from anywhere at anytime.  Matching the cloud service and the sync tool to your needs ensures your critical data is available even if your office is not.

3) Google Talk

With a laptop or smartphone, the Google Talk app, and an Internet connection anywhere, you can communicate with your team and your associates securely via instant messaging, voice conferencing, or video conferencing.  Don’t worry of phone lines or in-house PBXs are down, with Google Talk you can see who is available and converse at will.

4) Google Voice

Get your laptop to an Internet connection with a headset and microphone and you can send and receive calls without a fuss.

5) Hosted VoIP Phone Services

It may seem like the throw-back to the days of Centrex, but hosted VoIP (aka Hosted iPBX) services keep your phone lines working regardless of what is happening with your building.  And, you can access and use your lines, extensions, and voice mail from pretty much anyplace with either a VoIP phone, softphone software on your laptop, or your smartphone.

6) Cloud-Based Email

If you are thinking of using the cloud as a contingency service because cloud-based email is going to be available when your in-house system goes off-line, why not make the more reliable service the one you use every day?  Do you need or want to keep your in-house server when a cloud-based service will be more reliable and more available?  Ok, it’s a loaded question … but still worth some thought.

7) Cloud File Services

Just as with cloud-based email, Cloud File Services will prove more reliable and available over time, and especially during emergencies.  Granted, you may have applications, and work flow issues that make using cloud file services as your primary file service impractical.  But, you will never know if you don’t take a look. And, many of these requirements work with the right local sync technology in place.

8) Google Apps for Business / Government / Education

There, I finally said it.  Google Apps gives you the reliability and availability of the cloud-based Gmail, cloud storage you can mirror or sync, Google Talk, Google Voice integration, and a cloud file service.  Better yet, Google Apps rolls these services into an integrated, affordable package with access from most any computer and smartphone.  Some of the solutions may require third party components.  But, when disaster strikes (and disasters will strike), why not have an IT Ecosystem that is resilient to available rather than you you need to recover.
