#CMG2015: Performance Paradise

leave a comment »

Do you work in Systems Performance, IT Benchmarking, or Capacity Planning ? Then (if you are not already) you definitely need to be a part of Computer Measurement Group !

Computer Measurement Group (CMG) is a not-for-profit, worldwide organization of IT professionals committed to sharing information and best practices focused on ensuring the efficiency and scalability of IT service delivery to the enterprise through measurement, quantitative analysis and forecasting.

For decades CMG has been a leading organization for the exchange of information among enterprise computing professionals. Anyone charged with the measurement and management of computer systems would benefit from membership in CMG.

We recently held our annual international technical conference in San Antonio, home of the Alamo and the amazing River Walk.

Where else can you enjoy multiple days learning from and sharing with a few hundred of the best performance and capacity people in the world ? !!!

We had a great mix of topics at this conference (Full Disclosure: I am the Program Chair of this conference) across many focus areas including Performance Engineering, Application Performance Management, Mobile and Web Performance, Mainframe Performance and Capacity Planning, Network Capacity and Performance, Storage, and much more.

Here’s just a small sample of some of the awesome presentations:

  • I Feel the Need for Speed
  • Managing the Datacenter as the Computer
  • Tackling Big Data
  • Performance Considerations for Public Cloud
  • Why is this Web App Running Slowly?

I was a speaker on two exciting panels. The first was on Hybrid Cloud. I discussed how the Fit for Purpose methodology can work when deciding on the right environmental mix of on-premise, off-premise, private, public cloud. Namely, the Best Execution Venue. The second panel was on advancing your career in the Performance area, where I had a few good stories to tell.

The key to this conference and to this group as a whole is the laser-like focus on all of the groundbreaking, state-of-the-art areas in IT — but with an extreme emphasis on how they relate to Performance and Capacity.

So we talked Cloud. But Cloud with Performance. We talked Analytics. But Analytics with Performance. We talked Testing. But Testing with Performance . . .

All of the learning is wonderful. But I would have to say, as we tend to say about all events, that the networking and sharing is the absolute best part. What a Wonderful World of a conference.

And CMG is not just an annual conference. It’s an organization that you can be part of year-round through webinars, papers, articles, journals, regional groups and even social media.

Working on this conference was like planning a wedding. They can only go off without a hitch with an outstanding team to make it happen. Now the honeymoon begins. Until next month when we start it all over again for #CMG2016 !

Back in Time with Oracle

with one comment

Some of you may know that this week was a very big one for “Back to the Future” movie fans. On Wednesday, Oct. 21, 2015, at 4:29 p.m., our today caught up to the tomorrow depicted in “Back to the Future, Part II.” In that 1989 film, a DeLorean time machine appears from 30 years in the past.

To those who love time travel, this is a really big deal. Some towns even went so far as to rename themselves to the featured city in the film. Ceremonies worldwide were performed at exactly 4:29PM.

And this reminded me of a benchmark result that was just published today by Oracle on the SAP SD benchmark.

As we move into newer digital workloads, some of the older industry benchmarks have gone by the wayside. Many of us have spent a lot of time analyzing these newer workloads and developing new metrics for them. But one classic benchmark is still extremely appropriate for many of today’s applications – and that is the suite of SAP benchmarks.

But this new Oracle result just published is clearly dated — even though it is a brand new result on a brand new Oracle SPARC system. The IBM Power Systems result with DB2 from over 1 year ago is over 2X better performance per core than this new Oracle SPARC result. (1)

What’s really exciting, unlike this new benchmark result, is that many of the predictions of the future in the “Back to the Future” movie were right on. But I am still waiting for the dog-walking drone.

Amazon, Don’t Be A Performance Amateur

leave a comment »

I read just this morning that La Guardia airport in New York, with its dilapidated terminals and long delays, will be at long last rebuilt by 2021.

The plans look promising and work has already started. With new taxiways, a train and a grand entryway, it will finally be something to be proud of. Major infrastructure certainly needed for one of the major big league cities in the world.

And to play in the big league, you need to have the right plans to study and analyze, and you need to know what you are talking about. Which is why I was so disappointed this morning to also read about some new performance claims from Amazon Web Services (AWS).

In an announcement of a new relational database offering, Amazon made claims that simply had me confused. Let’s take a look:

  • The claims mix up performance with price performance. Obviously this difference is pretty basic. And important — but especially important in this environment where AWS charges extra for database instances, storage, and I/O.
  • The claims mix up speed and throughput. This difference can be very important because in this environment there are only 3 AWS regions right now offering these services and network performance can be key.
  • The claims mix up general comparisons with other “existing solutions” with a comparison using one particular tool, SysBench, to one particular release of one particular database, MySQL 5.6.
  • The claims mix up whether any improvement is due to software or hardware while stating that special techniques were used on both. Need I say more.

To play in the big league majors you have the understand the complexities of the subject. By attempting to address performance of this new offering, AWS is clearly exhibiting minor stripes.

Have you ever been at that gate at La Guardia, I think it’s A1A, where you have to carry your suitcase down two flights of stairs to a small waiting room with no air?

What’s In Your Bag?

leave a comment »

With summer just beginning in this part of the world, vacations are on everyone’s mind. And for me, that means hiking.

I actually have a list of everything that should go into my hiking knapsack. It’s written on a scrap of an old envelope and was first used prior to my going up Mount Washington. Here’s what’s on it:

  1. The Electronics: compass, map, phone, headlamp
  2. The Emergency Food: trail mix and granola bars, extra water
  3. The Moleskin: for my big right toe
  4. The Defense: bear spray and pocket knife
  5. The Sweater: my old gray cashmere with the big holes
  6. The Support: my hiking poles
  7. Just In Case: bug net, bandages, extra wool socks, hat, gloves, rain pants and long underwear
  8. If I Get in Trouble: whistle and waterproof matches
  9. The Drug of Choice: Motrin — for my back
  10. May be needed at the end: After Bite and the hot tub

Without these, I’d be lost. Literally. Maybe even worse.

And I was reminded the other day that the same type of preparation I use for my hiking trips is imperative when preparing my laptop bag for a business meeting.

And I realized that in the end I bring pretty much the same stuff.

  1. The Electronics: chargers, pointers, batteries
  2. The Emergency Food: cereal bars and pretzels, in case they don’t feed you
  3. The Moleskin: calendar that is – to schedule the next meeting
  4. The Defense: quick wit and verbal barbs
  5. The Sweater: my nice black cashmere, for when the air conditioning blows
  6. The Support: list of other subject matter experts
  7. Just In Case: the cheat sheet with the latest POWER8 news, the titles of who will be at the meeting, and the fun-to-read magazine because you never know when you are going to have to wait
  8. If I Get in Trouble: AAA or American Express Travel
  9. The Drug of Choice: Motrin — for my head
  10. May be needed at the end: drink in the hot tub

Will the Real Benchmark Please Stand Up

leave a comment »

They are at it once again. Those imposter benchmarks.

You know. The ones that initially look and feel like real IT industry performance benchmarks.

But then you read the article again, you look a bit more closely and you realize. They are at it again.

So how can we detect and overcome this benchmark fraud ?

  • Make sure the names of the actual benchmarks are clearly stated. You know, something with letters like TPC, SPEC, SAP, STAC, . . .
  • Make sure the metrics are correct. You know, something like transactions per minute or number of users.
  • Make sure there’s a really good footnote with all the details. Just the data is not enough.
  • Make sure there is a link to the site about the benchmark and preferably the results.
  • Make sure that if you sense an imposter benchmark, find REAL data on the systems you are interested in. At an official benchmark or vendor site.  Or run the real workload as a client benchmark.

If you’re not seeing these things, very likely it is some obscure testing that may or may not have a proper benchmark kit, audited results, etc. And it may very likely be artificially tuned to exploit only certain hardware or software that the imposter is looking to promote.

An industry benchmark masquerader that is actually a tried and true swindler.

World Peace . . . and Cloud

leave a comment »

I was reading an article in the paper this morning on reactions to the riots and looting in the city of Baltimore. And one point struck me – citizens of nearby neighborhoods seemed at a loss for what they could do to help their poverty-stricken neighbors. The comments the journalist kept hearing over and over again were essentially — Yes, but what can I do ?

Sometimes it’s hard to go from thinking about big problems strategically to tactical methods with concrete steps.

And that reminded me of something I’ve been seeing in IT lately, specifically in the area of transforming a system to a cloud.

A lot of us get hung up on the long term strategic big ideas, dreams, and wishes for our infrastructure. In 10 years I want to be able to . . . I envision a world where our data . . . In the future I will connect this system to . . . I will manage and control and orchestrate — someday.

In reality, we can get started on our dreams with 3 simple steps:

  • 1. Understand the Roadmaps for hardware and software on your current system and any new products being considered – What is supported now and in the future?
  • 2. Determine which hardware and software in your environment is appropriate to contain in your private Cloud.
  • 3. Create your private Cloud management system to MANAGE your infrastructure by either employing a tool such as IBM Power Virtualization Center (PowerVC) or creating an OpenStack tool of your own. Use this system to manage your compute (creating LPARs…), storage (managing SAN…), and network (allocating LUNs…) infrastructure. Start right now.

Now you have your private cloud and can consider some advanced steps:

  • Adopt a Cloud CONTROL and project management system such as IBM Cloud Manager with OpenStack for a self-service portal to create accounts and assets with a single pane of glass.
  • Consider implementing advanced ORCHESTRATION with a tool such as IBM Cloud Orchestrator to provide the capability of facilitating more complex workloads necessary to deploy reusable pattern solutions and take advantage of libraries associated with deploying more advanced cloud capabilities.

Then you are on your way with a sophisticated private cloud environment. Connect these systems of record and insight to your systems of engagement, potentially in the public cloud space, and you now have a full Hybrid environment.

As for Baltimore, it’s amazing to me that people seem to think they need to do everything or do nothing. Every little thing can help. Work with a student who can’t read. Donate some time or assets to a non-profit. It doesn’t have to be that hard.

My Washing Machine and 5 Myths on Cloud

leave a comment »

It was finally time. My clothes washer had been shaking for months. I actually resorted to running everything on Delicate. Tried to fix it. Put rubber pads under it. And then it finally danced off across the floor. And stopped.

Like many appliances, when you look at new washers there are so many things to compare. Front loader vs. top loader? Regular vs. High Efficiency? Agitator or not?

Of course I went to social media to get the 411. And what I found is that many consumers love a certain brand or model. Or hate it. And there is altogether too much customer sentiment on minor features that you may not even care about. Like lid locks.

Lid locks keep you from opening the washer easily to add more clothes. Something I never do. And something I really don’t care about. But it seems that some people really care an awful lot about lid locks. The point is – should I make my decision based solely on this narrow view?

And that’s what I have been seeing lately on Cloud. Like taking a narrow view of infrastructure platforms. Like limiting cloud scope to virtual public cloud only. Like forgetting that Cloud should be tactical and strategic, where performance, security, and compliance are key.

Here are 5 myths I’ve seen:

  • Cloud means only infrastructure. FALSE. Don’t forget software and business applications via the Cloud, a whole Marketplace.
  • Cloud means only public cloud. FALSE.  As we know, public cloud is a great enabler but on-premise private platforms are imperative for critical business systems of record.
  • Cloud means x86. Or AWS. Or Azure. Or . . . FALSE. Higher-end systems such as Power Systems and System z are of course leaders in private on-premise cloud. Power is also an outstanding choice on the public side, via SoftLayer or Cloud Managed Services.
  • Cloud means cheap public virtualized cloud. FALSE. Do the math. Some public cloud options can initially look inexpensive – but watch the hidden costs. Check out what it costs to actually access or move data. You may be surprised by the TCO you calculate.
  • Cloud means good for everything. FALSE. Match your workloads to the best technologies. Public cloud is not right for everything. Private cloud is not right for everything. Cloud is not even right for everything.

Make sure to focus on the full scope of cloud infrastructure platforms, the numerous choices offered, and the full suite of IBM’s cloud portfolio, on-premise and off-premise.

In the end, my new washing machine had a lid lock. But only because it happened to come with one.
