When the Application Stops Flowing, What Next?

Don’t you hate it when you have a problem, but have no idea what is causing it? The water in my house stopped running recently. I have a well with a pump and a fairly complex system of pipes going through a water filtration and softening system. I had no idea why the water was not flowing, but it was obviously a major issue.

I checked the pipes and they all seemed ok. I cleaned the filter, and verified that the water filtration system was in good order. While I cannot physically inspect the pump because it is dozens of feet down a 4-inch well shaft, I did power-cycle it to ensure that it seemed to be working properly. Ultimately, I had to call a plumber/well specialist who, after inspecting the entire system, determined that my water pressure tank and switch needed to be replaced.

Use Application Delivery Technologies to Accelerate and Automate the Boring Tasks

Playing a stringed musical instrument like a guitar means that the different strings need to be regularly adjusted to play the correct note. Guitar players tightened and loosened the strings to tune the guitar. The strings were tuned by ear, which meant that the person tuning the guitar had to know what sound each string had to make with considerable accuracy.

With modern technology, there are tuners that can generate tones so one no longer needs to know exactly what each note sounds like. And, today, there are tuners that will automatically adjust the tension in the string to create the right tone with no human intervention. This is a great benefit for guitar players because they like to play music, and not spend a lot of time and effort tuning their instrument every time they wanted to play.

Application Virtualization – Seeing the Forest Instead of Trees

February 2, 2017 — by Frank Yue0

Virtualization of the application environment is on every business’ mind. Terms like hypervisors, virtual machines, and software defined [insert your own popular term here: networks|data centers|storage] are being thrown around the technology industry like hot potatoes. While IT organizations focus on virtualizing specific applications, they often forget to see how this component fits into the overall trend to virtualize the entire IT infrastructure.

Automation – Virtualizing the Human Factor

December 8, 2016 — by Frank Yue0

Everyone is forgetting to virtualize the most important element within the IT environment – the humans. Virtualization through cloud, software defined networking (SDN), and software defined data centers (SDDC) is the latest craze with internet architectures. IT organizations are moving away from proprietary hardware towards common off the shelf (COTS) platforms that can perform a variety of tasks.

The hardware and software have been virtualized, but the “humanware” is racing to catch up to support the capabilities of the virtual infrastructures. Manually manipulating the virtual networks with manual processes is not efficient. Organizations lose much of the benefits of these virtualized application delivery architectures when human-driven manual processes are still used to support them.

Hybrid Cloud – It is Not the Migration that Hurts

November 15, 2016 — by Frank Yue0

The last time I moved was 10 years ago. At the time, I told myself that this is the last time I am moving. The packing and relocation of my belongings was not too much trouble. The main problem is trying to get everything sorted out and put into their proper place in the new home.

When businesses migrate applications to the cloud, the process is similar. They are very familiar with the applications and their data. The problem is that they need to understand how the applications will behave in the new environment. Where does the data reside and how do the clients access the application’s new home?

Hybrid Cloud is Not the Goal – A Case for Full Virtualization

November 10, 2016 — by Frank Yue0

In the world of cloud and virtualization, the buzz word of the day is ‘hybrid’. Everyone wants a hybrid cloud environment because they want to get the benefits of the cloud without relinquishing control of their applications and infrastructure. IT departments want the cost savings along with the agility and elasticity that cloud technologies bring, but they are not comfortable with the complete migration of their applications and data to a managed infrastructure.

Today, there are two primary use cases where companies are putting applications and data into the cloud. The difference between the two cases depends on whether it is an existing application or a new one that is being deployed. In the former, there is legacy infrastructure and support that has to be accounted for while the latter provides a greenfield opportunity to create an ideal infrastructure from the start.

Henry Ford was Right – Automation is the Key

Automobile manufacturers initially sold cars to wealthy families.  The automobiles were expensive and uncommon because the production of the vehicles was labor-intensive and took a long time to produce.  Henry Ford changed the way cars were built by moving from individual teams that required the time and expertise to build a car from start to finish, to a process that automated the assembly line with people owning individual tasks along the assembly line.

Load Balancing in the Cloud (with Diamonds)

Load balancing technologies are still needed when businesses put their applications in the cloud. One of the primary reasons people are putting their applications in the cloud is because they want the applications available anytime and anywhere.

The cloud infrastructures are designed to provide a unified service that makes their applications available without having to understand or deploy many of the complex technologies that provide application availability and resiliency.

My Load Balancer is a Swiss Army Knife

I am a self-professed nerd or geek. I like technology and what it can do for me. I like to go to the electronics store looking for items that I need want. When comparing the different models and brands, I will tend to drift towards the higher-priced gadgets that have all of these great features in addition to the function that I need.

For example, I recently purchased a Swiss Army knife. I needed a new pocket knife and wanted something that was functional and versatile. The knife I ended up buying has two knives, a screwdriver, can opener, bottle opener, corkscrew, wood saw, awl, toothpick, and tweezers. It is nice to have all of the additional functionality if I need it. But, in reality, 99% of the time I use my Swiss Army knife just to cut things with the knife blade.
