A couple of weeks ago, you might have noticed that eXpresso went dark for about two and a half days. The cause of our outage was directly connected to a rare but large scale outage Amazon’s ‘EC2′ and ‘EBS’ services suffered, making those services completely unavailable. And since eXpresso utilizes Amazon’s Web Services to host our application, Amazon’s problem became our problem. While it would be easy to point fingers and say, “It wasn’t our fault,” an honest assessment would suggest that is not entirely true, and shirking any responsibility would be doing a disservice to our customers.
First, let me explain a little of the jargon here. Amazon created an internal architecture to provide a highly available and quickly expandable system to host the various Amazon.com sites and sub-sites. While we are not privy to the inner workings of Amazon, we can only imagine someone looking over their work and saying, “Wow, this is really neat. We should commercialize this!” Thus, Amazon moved into the world of virtual hosting. In a traditional hosting environment, you lease a physical box (or boxes) to run your stuff on. If you could walk around the hosting facility, you would be able to walk up to a server, and say, “That is my server.” In a virtual hosting environment, you typically share a physical server with a few other people. The physical server runs special software, so that it can offer up many smaller virtual hosts to clients. To the outside world, each of these virtual hosts is just like a real physical machine. There are many benefits to virtual environments, but there are also some drawbacks – as with everything, the benefits must be weighed with the risks to determine what makes sense. We’re not going to delve into that discussion here. Amazon’s EC2 service is their virtual server offering and using it enables companies (like eXpresso) to create and manage server farms very easily. Amazon’s EBS offering is a similar virtual product line, except for disk drives, rather than servers. Add EC2 and EBS together, and you have a basic server that you can use to host your application.
Earlier in the year, eXpresso realized that while our software would expand nicely to meet our projected customer needs, the server platform that we were employing would not. After a good amount of research and internal arguments and debate, we made the decision to migrate our infrastructure to Amazon’s EC2/EBS service. We moved it all into “the cloud” because, in our case, the benefits far outweighed the risks. It all worked wonderfully, right up until the moment Amazon crashed. Ultimately, we got too complacent. If you look at Amazon’s infrastructure, it is highly redundant at the component level. If a physical server fails, another just takes over, invisibly. The same with hard drives. If one fails, another just takes over. No action required. No need to worry about hardware failures, right? Wrong. That’s the one thing we never had a plan for – what if the whole system fails? What if the piece of Amazon that we sit in falls over? In truth, we considered it, but dismissed it into the “never going to happen” category. That was our mistake, and one that bit us. Hard.
Ultimately, if you read Amazon’s post mortem (http://aws.amazon.com/message/65648/) you will see that this whole mess was caused by human error. It’s hard to plan for that, but it is reasonable to plan for the consequences of human error. We have taken a good, hard look at our decision to use Amazon, and the cloud in general, to host our platform. We stand by that decision and believe it continues to be right for us and for our customers. However, we have already improved, and will continue to improve, our systems to ensure that should such an event happen in the future, it will have minimal impact or ideally no impact whatsoever on our users. The steps we are taking are based upon mirroring our whole system to another geographic location, as well as replacing and duplicating other aspects of our infrastructure to ensure complete redundancy.
We apologize to our customers who were affected by this event. We recognize that this time we got lucky with the bulk of the outage occurring on a weekend – a relatively quiet time for us, but it was still totally unacceptable. We are determined that this kind of an outage will not happen again and are taking all the necessary steps to make it so.
Email has proven to be the first killer app for cloud computing, and today businesses can choose to rent email as a service from IBM, Microsoft, Google, Oracle, Cisco, or numerous smaller vendors. It is the first step in a larger shift in which, over the next decade, much of the computing and data storage that takes place in corporate data centers will migrate to the cloud. Now that our emails are “up there”, our documents are next, and vendors are battling to provide the leading cloud-based solution for documents because, let’s face it, if you manage a company’s email and their documents, you have them locked in.
However, online storage is only part of the value that business users want from the cloud when it comes to their documents. They also want to be able to collaborate with other users, and they don’t want to be forced to use a different office productivity suite. Oh – they also expect their files and those files belonging to their collaborators to render perfectly regardless of the format the file was created in. At eXpresso, we know this because we’ve been engaged with customers that have told us these things for the past 4 years.
With budgets constantly scrutinized, the software giants and not-so-giants who are contending for the title of Collaboration King will need to accommodate a world where their users need to collaborate with something other thanMicrosoft Office. That’s just a fact. They will need to support the complex fabric that is today’s computing landscape. Every collaborative interaction that involves documents will potentially involve a different blend of operating systems, office productivity suites, file formats, and browsers.
eXpresso has been working tirelessly to prove that such a world is possible, and today we have a working prototype ready to show to the world. (See Figure 1)
Figure 1
Notice that these two users have completely different computer environments. I should also add that this prototype makes use of IBM LotusLive as the collaboration backbone and that eXpresso will be available to all LotusLive users in the near future. What’s more, it shows the hybrid model that we believe in at eXpresso, where the desktop productivity resources of MS Office or Lotus Symphony are leveraged by our web-based document collaboration framework. The benefit of this is that each user gets to view or edit the file with their suite of choice, and the file’s original format is preserved with full fidelity.
eXpresso’s methodology and framework allows us to plug into almost any collaboration backbone and leverage almost any desktop productivity suite. This allows our users to keep using the software that they choose, while being able to collaborate with others in real-time without the drawbacks of Google Docs or the manual check-in/check-out model that is prevalent throughout the collaboration backbones available today.

Office 2010: Desktop Heavyweight, Online Weakling
“Microsoft’s suite upgrade is solid. But the accompanying Web Apps are surprisingly puny.”
Microsoft Office recently introduced the Web app version of Office 2010, but according to this article, it’s lightweight and fails to provide a compelling low-cost collaboration solution that appeals to business users. Businesses were hoping for cloud-based Office collaboration without being forced to take a step backwards with functionality. That’s why our customers end up choosing eXpresso. Not only does eXpresso enable multiple people to view or edit the same Office document online at the same time, eXpresso maintains the features and fidelity you are used to in your desktop version of Microsoft Office.
Advantages over Office 2010 Web Apps:
- More Functionality — eXpresso adds a layer of technology to Microsoft Office, so not only can you keep using the applications you are familiar with, you gain greater control over who can do what to the files you share.
- Less Complexity — SharePoint 2010 requires expertise, plus companies must figure out the subsequent details and resources involved with managing servers. For companies that already have SharePoint, it will require another upgrade and no doubt modified configurations, but for those who do not, it brings up more questions than it answers.
- Not forced to upgrade — you, your coworkers, clients, and other collaborators will not need to buy the 2010 upgrade to get the ability to edit files online. eXpresso is compatible with Office 2003 and 2007, which is what most Office users already have today.
- No additional unpredictable costs — SharePoint installations alone typically introduce countless hours of setup, training, maintenance, resource investment, and more. In contrast, eXpresso provides an easy-to-manage annual subscription for you or your company. Multi-user discounts available.

Forrester: Google still a distant Office competitor
“For all the noise about — and from — Google giving Microsoft a run for its money in the office/productivity market, the reality is rather different, according to Forrester Research.”
Customers come to eXpresso because they are looking for cutting-edge collaboration for the Office productivity applications they already use. In their search, they discover Google Docs provides real-time collaboration for documents but lacks the features and fidelity to make it a viable business solution. As the article indicates, Google Docs is a handy application for sharing basic information with friends, but when it comes to business, it simply does not deliver the solutions and capabilities necessary. eXpresso can.
Advantages over Google Docs:
- File Fidelity — Customers constantly tell us how their files lose formatting when imported into Google Docs. With eXpresso, you get all the benefits of real-time editing without sacrificing the integrity of your files.
- Familiar Interface — Customers also tell us how they like the concept of Google Docs, but they wish they could do it for Office instead. That’s eXpresso: real-time collaboration for Office documents stored in the cloud.
- Office Functionality — You won’t have to compromise features to gain collaboration. Keep using the Office application you already have installed. There’s no need to switch to a less functional Web app.
- Off-line Editing — Since Office is already on your machine, you can create new files or checkout existing ones when you’ll need to do some editing on the road.
- Smarter Real-Time Interaction — Like Google Docs, you can simultaneously edit files in real-time, but with eXpresso, you don’t need to see everyone’s micro-changes. Our methods for real-time document collaboration are efficient and much less distracting.
eXpresso is very excited about adding support for IBM Lotus® Symphony™ as an additional option for editing documents online. Our initial support for Symphony will be to LotusLive users. LotusLive is a business collaboration platform where people can do many different things, including share files. Our mutual goal with IBM is to enable LotusLive users to easily open and edit their stored files with whichever editor she or he prefers.
