1. Comparison of commercial cloud implementations

2. “In a recent Virtustream/Forrester survey of more than 700 cloud decision makers, 86% of respondents said that their enterprises are deploying workloads across more than one CSP. We learn from the same survey that the prime motivation for adopting a multi-cloud strategy is to improve performance, followed by cost savings and faster delivery times. Today, the three leading CSPs are Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), with respective market shares of 62%, 20%, and 12%”

3. Difficulties in selecting cloud platforms
Information is relatively hard to find
Most information provided by the companies themselves is aimed at selling
Especially pricing options are really vague for some companies
Terms and names for technologies vary, making it harder to categorize them
Larger applications need broad selection of services and features
Load balancing, scaling, databases, analytics, monitoring, push notifications etc.
It’s hard to find the service, that has it all, is easy to use and is the cheapest
Talking to colleagues in different companies working on different stacks, this really is an issue
Google had great summary, IBM wanted you to contact sales

4. Pricing models Pay-as-you-go Subscription Pay-for-Resources
Customer only pays what they use
Most used pricing model for Cloud
Customer may end up paying more than necessary
Subscription
Pay-for-Resources
Cost based model, fair for both customer and provider
Hybrid Models
Subscription, but the amount exceeding set limits is billed as pay-as-you-go
Fair for clients
As pricing of the cloud services is constantly evolving it’s not relevant to dive too deeply to the price models offered by different providers, but the different schemes are good to understand
Study referenced here lists lots of different pricing models. but the ones listed are the ones that are used on the platforms compared here

13. Takeouts for the course
Cloud platforms are developing in a accelerating rate and new platforms rise all the time
It’s important to try and find the differences and pros and cons of services instead of getting familiar with one spesific service
Pricing shouldn’t be a priority at all, but it’s good to mention that different (and sometimes confusing) models exist, and that the pricing is one key factor in ”the real life”
Some comparison of the free-tiers and student discounts of different platforms might be helpful to encourage hobby projects
