When building DevOps or continuous delivery practices you can learn a great deal from others. What choices did they make, what practices did they put in place, and how did they connect the dots? At Sonatype, we pulled together a set of 21 reference architectures for folks building ...
In a series of articles, I am going to share my thoughts on the state of IT infrastructure and how we've arrived with current architecture trends. The topic today is SAN. Storage Area Networking (SAN) is a technology that solved a real problem that existed a couple decades ago. SANs h...
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 bett...
Agile development is highly iterative, and relies upon the rapid development of software and early feedback. These practices are well understood and practiced in mature application development teams. The shift to an agile software development process has helped teams accelerate time t...
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 p...
Before becoming a developer, I was in the high school band. I played several brass instruments - including French horn and cornet - as well as keyboards in the jazz stage band. A musician and a nerd, what can I say? I even dabbled in writing music for the band. Okay, mostly I wrote ...
The burgeoning trends around DevOps are translating into new types of IT infrastructure that both developers and operators can take advantage of. The next BriefingsDirect Voice of the Customer thought leadership discussion focuses on the burgeoning trends around DevOps and how that’s ...
Data centers have seen a lot of change in a short time. It used to be possible for organizations to run their service from a single data center and house their Domain Name Service (DNS) servers within it. It wasn’t an issue to have them in the same place, since if the data center went ...

I’ve been flying quite a bit lately and I started thinking about why apps should be built more like planes. This is not meant to be a deep and insightful blog but rather amusing so I hope you enjoy my perspective!
An organizational culture that prioritizes coordinated response to incidents is vital for monitoring and managing an IT infrastructure. Incident management won’t go smoothly if teams don’t want to or know how to coordinate their response to alerts. To break it down simply, a coordinat...
Application performance problems can be quite challenging to resolve and even more difficult to predict. In my role as Dynatrace Guardian Consultant - leading the implementation of APM best practices with our customers - I've experienced quite a few "head-scratcher" situations. In this...
When we talk about today's technology environments, we're mostly talking about complexity. In the past decade or so, there have been some big changes in the way IT manages its resources and responsibilities. Along with the changes in technology (virtualization, cloud computing and othe...
A very wise man in a movie once put it, “It’s good for a man to know his limitations.” When it comes to a computer system, it’s essential. Understanding your capacity is a healthy part of running a business. Any business must understand what it needs in terms of its personnel (and the...
While API virtualization is already over a decade old, many developers, testers, and decision-makers still misunderstand it. Virtual APIs create an environment that teams can use to mimic the characteristics of the production environment and create simulated responses from all APIs th...
Traditional infrastructure purchasing plans to over-provision for growth were based on the pain of scaling-out classic infrastructure architecture. Modern infrastructure solutions like hyperconverged infrastructure take away the pain of scaling out and allow IT departments to purchase ...

Whether you suffer from a diagnosed anxiety disorder or not, many of us who are responsible for deployments become uneasy when deploying code to production. Did my tests catch everything? What if something happens during a migration and I can’t rollback? Will that small code change cr...
Infrastructure complexity is not unique to enterprise datacenters. Just because a business or organization is small does not mean it is exempt from the feature needs of big enterprise datacenters. Small and mid-size organizations require fault tolerance, high availability, mobility, an...
Pokemon Go has stormed onto the scene this past week and the buzz is everywhere about it! However, being so successful in such a brief period of time can have a downside. Reports of players being unable to access services started appearing in relatively short order. Amazon's CTO jumped...
