Notability

I wrote a blog about Goodnotes was my handwriting app of choice, but when it was released, it was full of bugs.

In 2020 I switched from Goodnotes to Notability.

The handwriting apps continue to be at the top of the productivity charts in App Store. I find that neither app has been innovated over the last few years. I wrote about the power of digital handwriting back in 2018.

Three years later, I still find it powerful. However, the apps are relatively the same as three years ago.

AWS Certified Database

I passed the AWS Certified Database Speciality Exam in May. That makes my 11th AWS certification. The database specialty seems to have split out the database content from the Big Data exam, which was retired in April of 2020. I did SME work on this exam and completed several workshops before its release.

Update 4/8/2021:
I reviewed the acloud.guru course and it seems to cover the exam topics covered in the exam blueprint

With the removal of the Alexa Certification, I now have all 11 AWS certifications.

AWS Certified Machine Learning – Specialty Links

The Machine Learning exam is rather difficult, as discussed previously. The starting point would be the acloud.guru Machine Learning course or Linux Academy courses. Additionally is the training offered by AWS. A chunk of Machine Learning is data and data preparation, so please see my links from Big Data.

Here is a collection of links I put together which helped me with studying for the exam.

AWS Certified Machine Learning – Specialty

Image of AWS Machine Learning Speciality Certification

I passed the AWS Certified Machine Learning Speciality Exam on Monday. That makes my 10th AWS certification in the last 18 months.

The Machine Learning Specialty certification is unlike any of the other exams from AWS. The exam doesn’t just focus on AWS specifics but covers a wide range of Machine Learning topics. The exam blueprint provides a basis of this coverage.

The exam is probably the hardest of the 10 I’ve taken to date. The entire exam, I thought I know the material, but I don’t think I know it well enough to pass the exam. My score was good, and it satisfying to add this certification. For the Machine Learning exam, I put in well over 200 hours over the last six months and over 80 hours the four weeks before sitting the exam. Definitely think the Big Data Certification helped on the data preparation sections.

They’re a bunch of links I will share later this week, which I studied. In addition to all the reading, I did acloud.guru’s AWS Certified Machine Learning - Speciality, which provides 40% of the material required to pass the exam. The rest of the exam requires detailed knowledge of Machine Learning. I followed the learning track recommended by AWS for Data Scientist. I also did several sections from Linux Academy Machine Learning, including the great section explaining PCA. Lastly, I took the AWS practice exam. I did look at Whizlabs but was somewhat disappointed in their practice tests.

In 2020, I hope to get a project which will allow me to leverage Machine Learning in SageMaker to solve a complex customer problem.

What I Learned About GCP

I’ve been on AWS since February of 2009, and my first bill was for $1.21 for some S3 Storage. Recently, I wanted to understand the Google Cloud Platform, as people talk about Spanner, BigQuery, BigTable, and App Engine. I figured the best way to learn was to challenge myself with a Google certification exam.

Given all my AWS experience, I initially wanted to write a blog article about what I liked and disliked, but I don’t think it’s that simple. There are exciting things within AWS and Google. Both of the platforms are complex, so this by no means is exhaustive. It’s more of what I noticed in my first couple of logins to Google Cloud.

The first thing I noticed was outside the service names how familiar the services were, and it didn’t take much to understand the VPCs, IAM, Billing, monitoring, Kubernetes (GKE), and Storage. The service names are vastly different, where Google calls everything Cloud blah and AWS calls them AWS or Amazon blah. Most of the fundamental principles were the same, especially in primary services like Compute, Storage, and IAM. This terminology probably speaks more to multi-cloud, than anything else.

The second thing I found that the Google Cloud Shell in the browner was outstanding. Google Cloud Shell is a container running which gives you a fully functioning Linux shell with disk space. Cloud Shell can be used for files, configuration files like Kubernetes manifests, and to check out code repositories. The kicker is that it’s embedded into the service and is free. The closest thing AWS offers is the shell inside Cloud9 service, which comes with an added expense. The Cloud Shell is something I liked on GCP.

The third thing I noticed was this concept of projects, which is a folder construct. I’m not sure if I like it. I saw examples where people used seperate folders for dev, test, and Production in the same account. I would be a little concerned given how easy it would be to be in the wrong project and issue commands. I prefer my dev/test to be separate accounts from Production. So I don’t necessarily know if this is a good or bad thing, but trends toward dislike.

Next fourth thing I noticed was the firewall rules. AWS has both the concept of Security Groups and Firewalls (NACLS). GCP only has firewall rules. The rule structure is impressive, as it allows to target by service account, tags, IP addresses. I would have a concern in a larger environment that the Firewall Rule list would be overly complicated and difficult to read and manage. I much prefer smaller nested security groups on AWS. However, the flexible of the GCP Firewall is impressive. I want the concept of tags inside security groups within AWS. So firewall rules are something I liked.

The fifth thing I want to highlight is the instance configuration. While AWS offers fixed CPU and memory instances, GCP offers custom selections for memory and CPU. This could be very interesting if there are a low CPU and high memory workload. I didn’t see significant cost differences between an overprovisioned AWS resource vs. a custom GCP resource. However, I also didn’t do an in-depth, TCO analysis. Again, I see pros and cons to this and probably I am neutral on this subject.

The last thing is the UI. It is different from AWS, and it took some use getting used too. It’s very similar in my experience to the G-Suite Admin or other Google services. I found the configuration of computing to be more changing given it’s a single page with tabs, vs. the AWS workflow. However, other items like Storage seemed to be more friendly. It doesn’t make a lousy user experience. Again I am neutral on this topic, I learned how to use it.

Probably now you are reading this and looking for that summary or in conclusion section. I’m not going to provide it. I remember two decades ago when we wanted to stand up web servers in a data center for a project, and it was going to cost $5,000 before we wrote the first line of code. As struggling college students, this wasn’t going to happen. What I am going to say is to go build something. Its never been easier for a builder to make an idea come to life on a platform you prefer with minimum investment (free tier). If your game is running Cobol inside a Kubernetes container, go do it. If you hate infrastructure go Serverless. Cobol on serverless would me attractive, eh? The power is in your hands. If you don’t have any ideas, go get a cloud certification. There never been a better time for a technologist with cloud experience.

Several people in the forums and the Internet have made comments comparing the GCP ACE to AWS. I found that difficult of the exam compares to the AWS Solution Architect Associate combined with the AWS SysOps Associate exam.

Thank you Mattias Anderson for putting together an excellent course on acloud guru.
