That Other Single Point of Failure

Unless you’re in publishing or high-tech, it is likely that our entire organization is a single point of failure

When you’re a kid at the beach, you spend a lot of time and effort building a sand castle. It’s cool, a lot of fun, and doomed to destruction. When high tide, or random kids, or hot sun come along, the castle is going to fall apart. It doesn’t matter, kids build them every year by the thousands, probably by the millions across the globe. Each is special and unique, each took time and effort, and each will fall apart.

The thing is, they’re all over the globe, and seasons are different all over the globe, so it is conceivable that there is a sand castle built or being built every minute of every day. Not easily provable, but doesn’t need to be for this discussion. when it is night and middle of winter in the northern reaches of North America, it is summer and daytime in Australia. The opportunity for continuation of sand castles is amazing.

Unless you’re in publishing or high-tech, it is likely that our entire organization is a single point of failure. Distributed applications make sense so that you can minimize risk and maximize uptime, right? The cloud is often  billed as more resistant to downtime precisely because it is distributed.

And your organization? Is it distributed? Really, spread out so that it can’t be impacted by something like Sandy?

There are a good number of organizations that are nearly 100% off-line right now because there is no power in the Northeast. That was not a possibility, it was an inevitability. Power outages happen, and they sometimes happen on a grand scale (remember the cascading midwest/northeast/Canada outage a couple years back – that was not natural disaster, it was design and operator error). And yet, even companies with a presence in the cloud clustered their employees in one geographic area. There is a tendency amongst some to want face-to-face meetings, assuming those are more productive, which leads to desiring everyone be on-site. With increasing globalization, and meetings held around the world - long before I became a remote worker, I held meetings with staff in Africa, Russia, and California, all on the same (very long) day, and all from my home in Green Bay – one would think this tendency would be minimized, but it does not seem to be.

The result is predictable. I once worked as a Strategic Architect for a life insurance company. They had a complete replica of the datacenter in a different geographic region, on the grounds that a disaster so horrible as to take out the datacenter would be exactly the scenario in which that backup would be needed. But guess where the staff was? Yeah,  at the primary. The systems would have been running fine, but the IT knowledge, business knowledge, and claims adjustment would all have been in the middle of a disaster.

Don’t make that mistake. Today, most organizations with multiple datacenters have DR plans that cover shifting all the load away from one of them should there be a problem, but those organizations with a single datacenter don’t have that leisure, and neither of them necessarily have a plan for continuation of actual work. Consider your options, consider how you will get actual business up to speed as quickly as possible. Losing their jobs because the business was not viable for weeks is not a great plan for helping people recover from disaster.

Even with the cloud, there is critical corporate knowledge out there that makes your organization tick. It needs to be geographically distributed. It matter not what systems are in the cloud if all of the personnel to make them work are in the middle of a blackout zone.

In short, think sand castles. If you have multiple datacenters, make certain your IT and business knowledge is split between them well enough to continue operations in a bad scenario. If you don’t have multiple locations, consider remote workers. Some people are just not cut out for telecommuting (I hate that phrase, since telecomm has little to do with the daily work, but it’s what we have), others do fine at it. Find some fine ones that have, or can be trained to have, the knowledge required to keep the organizations’ doors open. It could save the company a lot of money, and people a lot of angst. And your customers will be pleased too.

The key is putting the right people and the right skills out there. Spread them across datacenters or geographies, so you’re distributed as well as your apps. And while you’re at it, broadening the pool of available talent means you can get some hires you might never have gotten if relocation was required.

And all of that is a good thing.

Like sand castles.

Meanwhile, keep America’s northern east coast in your thoughts, that’s a lot of people in a little space without the amenities they’re accustomed to.

Let's just nip the conflation of these terms in the bud, shall we?

"MIcro" is big these days. Both microservices and microsegmentation are having and will continue to have an impact on data center architecture, but not necessarily for the same reasons. There's a growing trend in which folks - particularly those with a network background - conflate the two and use them to mean the same thing.

They are not.

One is about the application. The other, the network. T...

As the world moves toward more DevOps and Microservices, application deployment to the cloud ought to become a lot simpler. The Microservices architecture, which is the basis of many new age distributed systems such as OpenStack, NetFlix and so on, is at the heart of Cloud Foundry - a complete developer-oriented Platform as a Service (PaaS) that is IaaS agnostic and supports vCloud, OpenStack and AWS. Serverless computing is revolutionizing computing. In his session at 19th Cloud Expo, Raghav...
The following fictional case study is a composite of actual horror stories I’ve heard over the years. Unfortunately, this scenario often occurs when in-house integration teams take on the complexities of DevOps and ALM integration with an enterprise service bus (ESB) or custom integration. It is written from the perspective of an enterprise architect tasked with leading an organization’s effort to adopt Agile to become more competitive. The company has turned to Scaled Agile Framework (SAFe) as ...
If you are within a stones throw of the DevOps marketplace you have undoubtably noticed the growing trend in Microservices.

This is a no-hype, pragmatic post about why I think you should consider architecting your next project the way SOA and/or microservices suggest. No matter if it’s a greenfield approach or if you’re in dire need of refactoring. Please note: considering still keeps open the option of not taking that approach. After reading this, you will have a better idea about whether building multiple small components instead of a single, large component makes sense for your project. This post assumes that you...

Monitoring of Docker environments is challenging. Why? Because each container typically runs a single process, has its own environment, utilizes virtual networks, or has various methods of managing storage. Traditional monitoring solutions take metrics from each server and applications they run. These servers and applications running on them are typically very static, with very long uptimes. Docker deployments are different: a set of containers may run many applications, all sharing the resource...

Sharding has become a popular means of achieving scalability in application architectures in which read/write data separation is not only possible, but desirable to achieve new heights of concurrency. The premise is that by splitting up read and write duties, it is possible to get better overall performance at the cost of a slight delay in consistency. That is, it takes a bit of time to replicate changes initiated by a "write" to the read-only master database. It's eventually consistent, and it'...
With so much going on in this space you could be forgiven for thinking you were always working with yesterday’s technologies. So much change, so quickly. What do you do if you have to build a solution from the ground up that is expected to live in the field for at least 5-10 years? This is the challenge we faced when we looked to refresh our existing 10-year-old custom hardware stack to measure the fullness of trash cans and compactors.

There's a lot of things we do to improve the performance of web and mobile applications. We use caching. We use compression. We offload security (SSL and TLS) to a proxy with greater compute capacity. We apply image optimization and minification to content. We do all that because performance is king. Failure to perform can be, for many businesses, equivalent to an outage with increased abandonment rates and angry customers taking to the Internet to express their extreme displeasure.
Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...
