My Retirement Message to All of You

Tom Petrocelli

Well, best to rip off the band-aid.

I’m retiring at the end of the year. That’s right, on January 1, 2021 I will be officially and joyfully retired from the IT industry. No more conferences, papers, designs, or coding unless I want to. Truth be told, I’m still pretty young to retire. Some blame has to be laid at the feet of the pandemic. Being in the “trend” industry also sometimes makes you aware of negatives changes coming up. The pandemic is driving some of those including tighter budgets. This will just make everything harder.  Many aspects of my job that I like, especially going to tech conferences, will be gone for a while or maybe forever.

I can’t blame it all on the pandemic though. Some of it is just demographics. Ours is a youthful industry with a median age of roughly mid to early 40’s. To be honest, I’m getting tired of being the oldest, or one of the oldest people in the room. It’s not as if I’m personally treated as an old person. In fact, I’m mostly treated as younger than I am which means a certain comfort making “old man” jokes around me. No one thinks that I will take offense at the ageism, I suppose. It’s not really “offense” as much as it’s irritation.

There will be a good number of things I will miss. I really love technology and love being among people who love it as much as I do. What I will miss the most is the people I’ve come to know throughout the years. It’s a bit sad that I can’t say goodbye in  person to most of them. I will especially miss the team here at Amalgam Insights. Working with Hyoun, Lisa, and everyone else has been a joy. Thanks for that you all.

My career has spanned a bit over 36 years (which may surprise some of you… I hope) and changes rarely experienced in any industry. When I started fresh from college in 1984, personal computers were new, and the majority of computing was still on the mainframes my Dad operated. No one could even imagine walking around with orders of magnitude more computing power in our pockets. So much has changed.

If you will indulge me, I would like to present a little parting analysis. Here is “What has changed during my career”.

  1. When I started mainframes were still the dominant form of computing. Now they are the dinosaur form of computing. Devices of all kinds wander the IT landscape, but personal computers and servers still dominate the business world. How long before we realize that cyberpunk goal of computers embedded in our heads? Sooner than I would like.
  2. At the beginning of my career, the most common way to access a remote computer was a 300 baud modem. Serial lines that terminals deployed to speak to the mainframes and minicomputers of the times were also that speed. The bandwidth of those devices was roughly 0.03 Mbps. Now, a home connection to an ISP is 20 – 50 Mps or more and a corporate desktop can expect 1 Gbs connections. That’s more than 33 times what was common in the 80s.
  3. Data storage has gotten incredibly cheap compared to the 1980s. The first 10M hard drive I purchased for a $5000 PC cost almost US$ 1000.00 in 1985 dollars. For 1/10 of that price I can now order a 4T HD (and have it delivered the next day.) Adjusted for inflation that $1000 HD cost ~$2500 in 2020 dollars. That’s 25 times what the modern 4T drive costs.
  4. Along with mainframes, monolithic software has disappeared from the back end. Instead, client-server computing has given way to n-Tier as the main software platform. Not for long though. Distributed computing is in the process of taking off. It’s funny. At the beginning of my career I wrote code for distributed systems, which was an oddity back then. Now, after more than 30 years it’s becoming the norm. Kind of like AI.
  5. Speaking of AI, artificial intelligence was little more than science fiction. Even impressive AI was more about functions like handwriting recognition, which was created at my alma mater, the University at Buffalo, for the post office. Nothing like we see today. We are still, thankfully, decades or maybe centuries from real machine cognition. I’ll probably be dead before we mere humans need to bow to our robot overlords.
  6. When I began my career, it was very male and white. My first manager was a woman and we had two other women software engineers in our group. This was as weird as a pink polka dotted rhinoceros walking through the break room. Now, the IT industry is… still very male and white. There are more women, people with disabilities, and people of color than there was then but not quite the progress I had hoped for.
  7. IBM was, at that time, the dominant player in the computer industry. Companies such as Oracle and Cisco were just getting started, Microsoft was still basically a garage operation, and Intel was mostly making calculator chips. Now, IBM struggles to stay alive, Cisco, Oracle, Intel, and Microsoft are the established players in the industry and Amazon, an online store, is at the top of the most important trend in computing in the last 20 years, cloud computing. So many companies have come and gone, I don’t even bother to keep track.
  8. In the 1980s, the computer industry was almost entirely American, with a few European and Japanese companies in the market. Now, it’s still mostly American but for the first time since the dawn of the computer age, there is a serious contender: China. I don’t think they will dominate the industry the way the US has, but they will be a clear and powerful number two in the years to come. The EU is also showing many signs of innovation in the software industry.
  9. At the start of my career, you still needed paper encyclopedias. Within 10 years, you could get vast amounts of knowledge on CD’s. Today, all the world’s data is available at our fingertips. I doubt young people today can even imagine what it was like before the Internet gave us access to vast amounts of data in an instant. To them, it would be like living in a world where state of the art data storage is a clay tablet with cuneiform writing on it.
  10. What we wore to work has changed dramatically. When I started my career, we were expected to wear business dress. That was a jacket and tie with dress slacks for men, and a dress or power suit for women. In the 90s that shifted to business casual. Polo shirts and khakis filled up our closets. Before the pandemic, casual became proper office attire with t-shirts and jeans acceptable. At the start of my career, dressing like that at work could get you fired. Post pandemic, pajamas and sweatpants seem to be the new norm, unless you are on a Zoom call. Even so, pants are becoming optional.
  11. Office communications has also changed dramatically. For eons the way to communicated to co-workers was “the memo.” You wrote a note in long hand on paper and handed it to a secretary who typed it up. If there was more than one person, the secretary would duplicate it with a Xerox machine and place it in everyone’s mailboxes. You had to check your mailbox everyday to make sure that you didn’t have any memos. It was slow and the secretaries knew everyone’s business. We still have vestiges of this old system in our email systems. CC stands for carbon copy which was a way of duplicating a memo. In some companies, everyone on the “To:” list received a fresh typed copy while the CC list received a copy that used carbon paper and a duplicating machine. As much as you all might hate email, it is so much better (and faster) than the old ways of communicating.
  12. When I started my first job, I became the second member of my immediate family that was in the IT industry. My Dad was an operations manager in IBM shops. Today, there are still two members of our immediate family that are computer geeks. My son is also a software developer. He will have to carry the torch for the Petrocelli computer clan. No pressure though…
  13. Remote work? Ha! Yeah no. Not until the 90s and even then, it was supplementary to my go to the office job. I did work out of my house during one of my start ups but I was only 10 minutes from my partner. My first truly remote job was in 2000 and it was very hard to do. This was before residential broadband and smartphones. Now, it’s so easy to do with lots of bandwidth to my house, cheap networking, Slack, and cloud services to make it easy to stay connected. Unfortunately, not everyone has this infrastructure nor the technical knowhow to deal with network issues. We’ve come a long way but not far enough as many of you have recently discovered.

So, goodbye my audience, my coworkers, and especially my friends. Hopefully, the universe will conspire to have us meet again. In the meantime, it’s time for me to devote more time to charity, ministry, and just plain fun. What can I say? It’s been an amazing ride. See ya!

Looking at Microservices, Containers, and Kubernetes with 2020 Vision

Kubernetes Icon

Some years are easy to predict than others. Stability in a market makes tracing the trend line much easier. 2020 looks to be that kind of year for the migration to microservices: stable with stead progression toward mainstream acceptance.

There is little doubt that IT organizations are moving toward microservices architectures. Microservices, which deconstruct applications into many small parts, removes much of the friction that is common in n-Tier applications when it comes to development velocity. The added resiliency and scalability of microservices in a distributed system are also highly desirable. These attributes promote better business agility, allowing IT to respond to business needs more quickly and with less disruption, while helping to ensure that customers have the best experience possible.

Little in this upcoming year seems disruptive or radical; That big changes have already occurred. Instead, this is a year for building out and consolidating; Moving past the “what” and “why” and into the “how” and “do”.

Kubernetes will be top of mind to IT in the coming year. From its roots as a humble container orchestrator – one of many in the market – Kubernetes has evolved into a platform for deploying microservices into container clusters. There is more work to do with Kubernetes, especially to help autoscale clusters, but it is now a solid base on which to build modern applications.

No one should delude themselves into thinking that microservices, containers, and Kubernetes are mainstream yet. The vast majority of applications are still based on n-Tier design deployed to VMs. That’s fine for a lot of applications but businesses know that it’s not enough going forward. We’ve already seen more traditional companies begin to adopt microservices for at least some portion of their applications. This trend will accelerate in the upcoming year. At some point, microservices and containers will become the default architecture for enterprise applications. That’s a few years from now but we’ve already on the path.

From a vendor perspective, all the biggest companies are now in the Kubernetes market with at least a plain vanilla Kubernetes offering. This includes HP and Cisco in addition to the companies that have been selling Kubernetes all along, especially IBM/Red Hat, Canonical, Google, AWS, VMWare/Pivotal, and Microsoft. The trick for these companies will be to add enough unique value that their offerings don’t appear generic. Leveraging traditional strengths, such as storage for HP, networking for Cisco, and Java for Red Hat and VMWare/Pivotal, are the key to standing out in the market.

The entry of the giants in the Kubernetes space will pose challenges to the smaller vendors such as Mirantis and Rancher. With more than 30 Kubernetes vendors in the market, consolidation and loss is inevitable. Expect M&A activity in the Kubernetes space as bigger companies acquihire or round out their portfolios. Kubernetes is now a big vendor market and the market dynamics favor them. There’s plenty of value in the smaller firms but it will be too easy for them to get trampled underfoot.

If there is a big danger sign on the horizon, it’s those traditional n-Tier applications that are still in production. At some point, IT will get around to thinking beyond the shiny new greenfield applications and want to migrate the older ones. Since these apps are based on radically different architectures, that won’t be easy. There just aren’t the tools to do this migration well. In short, it’s going to be a lot of work. It’s a hard sell to say that the only choices are either expensive migration projects (on top of all that digital transformation money that’s already been spent) or continuing to support and update applications that no longer meet business needs. Replatforming, or deploying the old parts to the new container platform, will provide less ROI and less value overall. The industry will need another solution.

This may be an opportunity to use all that fancy AI technology that vendor’s have been investing in to create software to break down an old app into a container cluster. In any event, the migration issue will be a drag on the market in 2020 as IT waits for solutions to a nearly intractable problem.

2020 is the year of the microservice architecture. Even if that seems too dramatic, it’s not unreasonable to expect that there will be significant growth and acceleration in the deployment of Kubernetes-based microservices applications. The market has already begun the process of maturation as it adapts to the needs of larger, mainstream, corporations with more stringent requirements. The smart move is to follow that trend line.
