#cloud Elasticity is a design pattern for scalability, not necessarily failability. One of the phrases you hear associated with cloud computing is "architecting for failure." Rather than build in a lot of hardware-level redundancy – power, disk, network, etc… – the idea is that y...
#devops #cloud Managing a global presence – especially in the cloud – can introduce additional complexity. Back in the day when virtualization and cloud were just making waves, one of the first challenges made obvious was managing IP addresses. As VM density increased, there wer...
#Microsoft #Exchange load balancing is just the beginning… Throughout the years, F5 BIG-IP has been a critical component supporting Microsoft Exchange to implement a variety of performance, security, and architectural requirements. During that time, we've seen Microsoft Exchange...
There's an unwritten rule that says when describing a network architecture the perimeter of the data center is at the top. Similarly application data flow begins at the UI (presentation) layer and extends downward, toward the data tier. This directional flow has led to the use of the t...
BYOD remains a topic of interest as organizations grapple not only technologically with the trend but politically, as well. There are dire warnings that refusing to support BYOD will result in an inability to attract and retain up and coming technologists, that ignoring the problems as...

#BYOD #infosec It's context that counts, not corporate connections. BYOD remains a topic of interest as organizations grapple not only technologically with the trend but politically, as well. There are dire warnings that refusing to support BYOD will result in an inability to attract...
#cloud The conventional view of cloud brokers misses the need to enforce policies and ensure compliance During a dinner at VMworld organized by Lilac Schoenbeck of BMC, we had the chance to chat up cloud and related issues with Kia Behnia, CTO at BMC. Discussion turned, naturally I ...
There are multiple trends putting pressure on IT today to radically change the way they operate. From SDN to cloud, market pressure on organizations to adopt new technological models or utterly fail is immense. That's not to say that new technological models aren't valuable or won't...

It may be heresy, but not every organization needs or desires all the benefits of cloud.  There are multiple trends putting pressure on IT today to radically change the way they operate. From SDN to cloud, market pressure on organizations to adopt new technological models or utter...
No, not colonial as in Battlestar Gallactica or the British Empire, colonial as in corals and weeds and virtual machines I was out pulling weeds this summer – Canada thistle to be exact – and was struck by how much its root system reminded me of Cnidaria (soft corals to those of you...

It should be noted that this is one – just one – Java EE application and even it is greatly simplified (architectural flowcharts coming from the dev side of the house are extraordinarily complicated, owing to the number of interconnects and integrations required). Most enterprises have...

One of the interesting side effects of having been a developer before migrating to a more network-focused view of the world* is it’s easier to understand the limitations and constraints posed on networking-based software, such as web servers. During the early days of virtualization ad...

One of the negative's of cloud computing is it's one-size-fits-all approach to infrastructure. A single load balancing system (and subsequently configuration) is considered acceptable for all applications. After all, it's just about distributing requests, isn't it? Except it isn't, ...
Adopting a cloud-oriented business model for IT is imperative to successfully transforming the data center to realize ITaaS. Much like devops is more about a culture shift than the technology enabling it, cloud is as much or more about shifts in business models as it is technology. E...
#vmworld #vdi #byod #infosec #F5 supports VMware’s latest VDI initiative: BPD  When remote office connectivity first became a reality there began to emerge a variety of requirements specific to needs of the business and remote users. Over top of point-to-point VPN connectivity we la...
#webperf #cloud With performance rising as a concern for cloud computing adoption, the disparity between services in the data center and the cloud needs to be addressed. One of the negative's of cloud computing is it's one-size-fits-all approach to infrastructure. A single load bala...
Every time there's a major technological shift in operational models you can here the hue and cry from across the land of IT: the sky is falling. Our jobs are in jeopardy. Technology "X" will eliminate the need for "Y". Like the children's fable of Chicken Little, the sky never falls,...
Infrastructure metrics have always been focused on speeds and feeds. Throughput, packets per second, connections per second, etc… These metrics have been used to evaluate and compare network infrastructure for years, ultimately being used as a critical component in data center design. ...

#webperf As we continue to find new ways to make connections more efficient, capacity planning must look to other metrics to ensure scalability without compromising performance. Infrastructure metrics have always been focused on speeds and feeds. Throughput, packets per second, co...
SDN is disruptive but it's not destructive, especially not at layer 4-7 In the wake of VMware's acquisition of SDN notable Nicira there was a whole lot of behind-the-scenes scrambling to understand the impact to the entire networking demesne – especially given speculation that after...

We use the term “hybrid cloud” to indicate a joining together of two disparate environments. We often simplify the “cloud” to encompass public IaaS, PaaS, SaaS and private cloud. But even though the adoption of such hybrid architectures may be a foregone conclusion, the devil is, as th...

No one argues that networks have not exploded in terms of speeds and feeds in the past decade. What with more consumers (and cows), more companies going “online”, and more content it’d be hard to argue that there’s less traffic out there today than there was even a mere four or five ye...
Yes, even the ones over there, in that there cloud, can be yours. No one argues that networks have not exploded in terms of speeds and feeds in the past decade. What with more consumers (and cows), more companies going “online”, and more content it’d be hard to argue that there’s les...
An old English proverb observes that "Even a broken clock is right twice a day.” A more modern idiom involves a blind squirrel and an acorn, and I’m certain there are many other culturally specific nuggets of wisdom that succinctly describe what is essentially blind luck. The proverb ...

Some idioms are cross-cultural and cross-temporal. They transcend cultures and time, remaining relevant no matter where or when they are spoken. These idioms are often referred to as proverbs, which carries with it a sense of enduring wisdom. One such idiom, “practice makes perfect”, c...
SDN and devops share some common themes. Both focus heavily on the notion of programmability in network devices as a means to achieve specific goals. For SDN it’s flexibility and rapid adaptation to changes in the network. For devops, it’s more a focus on the ability to treat “infrastr...
Reading “OpenFlow/SDN Is Not A Silver Bullet For Network Scalability” brought to light an important note that must be made regarding scalability and networks, especially when we start talking about the control plane. It isn’t that the network itself won’t scale well with SDN, the conce...
