The Dark Side of The Cloud

We all pay our monthly electricity bills. I am sure no one wants to own a power plant :) But, on the contrary most of us own cars and very few rent it for daily use.

The two most important factors which decide how we want to use these two services are -

  1. The cost of ownership
  2. The cost and effort in maintenance

Cloud computing today promises benefits (which are similar to using electricity) for computing, hosted application and storage. Although the offer is very lucrative, but their is a dark side to this as well.

The post just tries to some aspects which you must keep in mind before making the plunge.

The Dark Side of Cloud

The Dark Side of the Cloud

Application Integration

Most of the services like SimpleDB, EBS, SQS still needs a lot of application integration and porting. And that’s something enterprises hate. It’s one of the primary reasons the X86 architecture and IPV4 are so widely used. Even if someone ports the application to these services, he is guaranteed to be locked with it for the rest of his life :)

Services like salesforce.com don’t need any porting, but there have been cases of access to data being refused customers who wish to change the vendor.

Uptime and QoS Guarantees

Most of these services including Amazon and Salesforce do not give uptime and QoS guarantees. The billing and EULA are free from any such clauses.

And when there is a downtime, you can’t do much than start calling the support center to play the blame-game.  And its funny when see the the cloud provider talking the same language to its service provider :)

It’s No Way Even Close to Perfect

Take a recent unfortunate situation for Ylastic, a company that provides a single front-end to manage Amazon Web Services, who was recently an unwillingly participant in one of these cloud bursts. Ylastic noticed something strange occurring with one of the Amazon Elastic Cloud Compute (EC2) Elastic Block Stores (EBS).

But something wasn’t quite right. And over the course of a few hours the story played out via Twitter as Ylastic noticed issues with its EBS instances. When the problem was finally identified, Ylastic discovered that the data could not be recovered. They were forced to recover from an earlier snapshot, that contained only a subset of the data.

Finally, after recovering what data they could, Ylastic had to go to its customers with the unfortunate message:

“AWS has finally terminated the frozen instances. But the EBS volume is still detaching and has been for hours. It doesn’t seem like we will be able to get into it at this point. Some time in the last month or so, our EBS snapshotting of this stuck volume seems to have stopped working correctly…. We have gone back and run through all the snapshots, and the last good snapshot that we have is from October 1.”

Who was at fault? Amazon? Ylastic? Truly, no one. It was simply a combination of issues. A perfect storm in the cloud, as it were. And that perfect storm resulted in data loss for Ylastic and its customer base.

Control

Take for example the case when you take up a cheap hosted website plan on a shared server. You can still negotiate uptime and QoS guarantees. But, what you just can’t control is a SPAM King sharing the same server and IP address with you :)

Most likely you will face two problems -

  1. A slow response on the website- the SPAM King has taken up the computing
  2. Public mail servers will mark the mail traffic from you as spam :)

Plus, there been many stories around salesforce (read this and this) and twitter getting hacked.

ROI

Cost of ownership for a power plant is so damn high, that you just can’t afford one even if you are not happy with your power company. That exactly has to be the case for the cloud.  No one would think of hosting his own solution when the cloud offers the same peanuts.

Real Businesses Can’t Depend upon Just Tape Backup

The recent Journalspace data loss episode, is a good lesson for all of us. I don’t know what exactly went wrong, but it highlights the fact that real businesses today can’t depend upon only tape/disk based archival of business critical data.

IMO, a good data protection strategy should value following points -

  1. Clear understanding of RPO and RTO for data protection
  2. Local disk-based backup for faster recovery.
  3. Remote-Replication for disaster recovery
  4. Archival and e-discovery

In simple terms RPO (Recovery Point Objective) is – “up to what point in time the data can be recovered” and RTO (Recovery Time Objective) implies – “how much time would it take to recover data”. These goals differ from business to business. But, any real enterprise can’t depend on slow tapes for this, especially when it comes to critical customer data.

The two terms – “Backup” & “Archival” are often confused with each other. And as I see it going forward, more and more enterprises would use local disk based backup-recovery for lowering RPO & RTO. The Tape/VTL/Tape would only be used for archival of older and currently-not-being-used data for compliance or specific business reasons.

With remote IP-based replication almost becoming commodity now, it can easily be used to avoid any local disasters. But, it would be interesting to see it being integrated with local disk-based backup systems. This could reduce load on the production server and make recovery simple.

On the good side, I loved the CouchSurfing 2.0 Rised from the Ashes story covered by Luxman. The company lost the entire MySQL database almost two years back because of a faulty file-system. Founder & CEO Casey Fenton announced company’s death. Later, Fenton’s email was met with vocal opposition to the termination of the project and considerable support for its recreation.

“CouchSurfing 2.0″ was announced early in July 2006, with the intent to be operational within 10 days. The initial implementation of CouchSurfing 2.0 actually launched after only four days.

Laptop Backup Solutions Important to Enterprise Users: A Look at Search Engine Statistics

While doing some keyword research for Druvaa it began to become clear how interesting search engine statistic can be when you look closely at the data. From simple keyword suggestion tools, and graphs you can ascertain information that you never thought possible.

The terms “backup” or “recovery”, for instance, get over 300,000 searches per month each with Google. In other words people are searching for good solutions to keep their data safe. That information by itself is useful (at least to us), but it’s when you begin to look at more specific search terms that things really get interesting. In fact, you can even begin to clearly see trends within the industry when you compare specific terms over any given length of time.

With a look at some simple charts, you can begin to see things like:

  • 1. Interest in laptop backup solutions has greatly increased over the past 10 years.
  • 2. Some users are finding solutions to their data backup needs and disaster recovery isn’t as much of a problem as it was 4 years ago (but it still is a problem).
  • 3. Enterprise users who have laptops in the office are still seeking a suitable solution to their backup needs.
  • 4. Enterprise users who have offsite backup needs are still seeking a solution to business continuity.

To demonstrate how I can get all of that from a few search terms, let’s take a closer look at some charts.

A Look at Trends Using Search Engine Statistics

Using Google Labs and their experimental search tool you come up with the following charts for the terms “data backup” and “laptop backup”.  This particular tool uses search volumes, online news statistics, number of websites, and more to show interest in any given topic. The charts clearly show that, while data backup has retained the same amount of interest over the past 10 years, interest in laptop backup has (and is) increasing.

Data Backup - Search Term Timeline

Laptop Backup - Search Engine Timeline

Of course, this idea makes sense. Laptops have decreased greatly in price since 1998, and as such have become a more common tool both for enterprise users and at home. On the other hand, data integrity has been a problem for business users for a couple of decades now, so interest in the topic of “data backup” have remained relatively the same.

This information alone isn’t necessarily new. It’s the reason we created Druvaa InSync in the first place. The industry needed a reliable data backup solution, which is also fast enough to work well with computers that are on the go.  To further look at what’s needed let’s look at some more charts. This time based on search volumes alone.

Laptop Backup as Important as Ever

Search volumes for any given term are an easy way to see what is happening within an industry, to gauge interest for a product or service, or even to see how one product relates to another. In the developed world more than 73% of the population has internet access, and over 88% of internet users go online when they seek a solution to a problem.

With that in mind let’s briefly look at some search engine statistic.  In this case I have used Google Insights to compare related search terms. The charts are based on normalized data, over time. If you looked at the actual search volumes they would have increased with time (since Internet use has grown). To get a more accurate look, Insights uses normalized data displayed on a scale of 1 – 100.

Data Backup vs Disaster Recovery

The first chart compares the terms data backup and disaster recovery. There are two things that can be gained from this chart.

  • 1. Since search volumes for both terms have declined over the past few years, it shows that some users are finding solutions to their backup needs, and disaster recovery is less of a problem today than it was in 2004/2005.
  • 2. As the lines of the chart come together, they begin to show a direct correlation to each other. Very likely this is due to the fact that proper data backup is becoming the solution to disasters in the office. It really was only a few years ago that disaster recovery often meant taking that broken hard drive to have the data extracted. In the past couple of years, enterprise users have begun to see that simple backups are a cheaper (and more reliable) solution.

Since the term data backup may also relate to home users, with the next chart I used the term “enterprise backup” and compared it to “laptop backup”. Again we can see a couple of things from this chart. Once again we see a slight decline in the search volumes for enterprise backup. This confirms the idea that some enterprise users are finding a suitable solution to their backup needs.

Laptop Backup Vrs Enterprise Backup

By adding the term laptop backup though, something else begins to become clear. The term started the chart off at 61 and finished three years later at 62. There have been slight ups and downs in search volumes, but overall they have remained relatively the same. The two terms also begin to correspond closely with each other as the chart moves through 2007 and into 2008. To me this says that these terms are also beginning to become synonymous.  In other words, although some enterprise users are finding a backup solution, those with laptops in the office aren’t.

I could repeat these same results with terms like “offsite backup” or “remote backup”.

With a simple look at search engine statistics we begin to see that enterprise users have a need for a laptop backup solution that works. With our own product, which provides 10x faster laptop backup and a 90% reduction in storage and bandwidth, there is a solution to suit.

Understanding RPO and RTO

Recovery Point Objective (RPO) and Recovey Time Objective (RTO) are one of the most important parameters of a disaster recovery or data protection plan. These objectives guide the enterprises to choose a optimal data backup (rather restore) plan.

RPO – Recovery Point Objective (wikipedia)

“Recovery Point Objective (RPO) describes the amount of data lost measured in time. Example: If the last available good copy of data upon an outage was from 18 hours ago, then the RPO would be 18 hours.”

In other words if the answer to question – Up to what point in time could the data be recovered ?.

RTO – Recovery Time Objectives (wikipedia)

“The Recovery Time Objective (RTO) is the duration of time and a service level within which a business process must be restored after a disaster in order to avoid unacceptable consequences associated with a break in continuity.

It should be noted that the RTO attaches to the business process and not the resources required to support the process.”

In another words its the answer to question – How much time did you take to recovery after notification of business process disruption ?

The RTO/RPO and the results of the Business Impact Analysis (BIA) in its entirety provide the basis for identifying and analyzing viable strategies for inclusion in the business continuity plan. Viable strategy options would include any which would enable resumption of a business process in a time frame at or near the RTO/RPO. This would include alternate or manual workaround procedures and would not necessarily require computer systems to meet the objectives.

There is always a gap between the actuals (RTA/RPA) and objectives introduced by various manual and automated steps to bring the business application up. These actuals can only be exposed by disaster and business disruption rehearsals.

Some Examples –

Traditional Backups
In traditional tape backups, if your backup plan takes 2 hours for a scheduled backup at 0600 hours and 1800 hours, then a primary site failure at 1400 hrs would leave you with an option to restore from 0600 hrs backup which means RPA of 8 hours and 2 hours RTA.

Continuous Replication
Replication provides higher RPO guarantees as the target system contains the mirrored image of the source. The RPA values depend upon how fast the changes are applied and if the replication is synchronous or asynchronous. RPO is dependent on the fact that how soon can the data on target/replicated site be made available to the application.

Druvaa Replicator
Druvaa Replicator is Continuous Data Protection and Replication (CDP-R) product which near-synchronously and non-disruptively replicates changes on prodhuction sever to target site and provides point-in-time snapshots for instant data access.

The partial synchronous replication ensures that the data is written to a local or remote cache (caching server) before it application can write locally. This ensures up to 5 sec RPO guarantees . CDP technology (still beta) enables up to 1024 snapshots (beta) at that target storage which helps the admin to access current or any past point-in-time consistent image of data instantly, ensuring under 2 sec RTO.
