3. Theory

4. What is the cloud?
- On-demand
- Pay-as-you-go pricing
- Remote servers
- Cloud is an alternative to on-premises
(pol. “lokalne / w terenie”) DC: private
group of servers that a company owns
and maintains

5. What really is the cloud?
- “It’s like LEGO bricks (services) - that you can build
together”
- Build fast incredible applications - that need to be
- Scalable
- Reliable
- Created for companies that didn’t have money for
big datacenters (e.g. startups)
- Good for company of any size

6. Types of clouds
- Public: cloud infrastructure operated for multiple organizations
- Private: cloud infrastructure operated for a single organization
- Hybrid: public cloud + private cloud

7. Types of cloud services
- IaaS - base infrastructure - end users have to deploy apps, manage platform and others- e.g. AWS
EC2
- PaaS - platform allowing end users to develop, run, and manage applications without building and
maintaining the infrastructure - e.g. AWS ElasticBeanstalk
- SaaS - everything is managed
by vendors, end users simply
access software via browser
(Gmail)
- FaaS - platform for application
functionalities (Lambda,
Google Cloud Functions)

8. Regions / Zones (AWS based)
- 31 Regions (5 more planned in e.g. Israel, New
Zealand, Thailand)
- Each Region is designed to be isolated
from the other Regions
- Frankfurt - eu-central-1
- 99 AZs
- Multiple (usually 3, min 2), isolated
locations within each Region
- AZ - one or more DCs with redundant
power, networking and connectivity. AZs
are physically separated by a meaningful
distance from any other AZ
- AZ for Frankfurt - eu-central-1a
- Local Zones
- Extensions of a Region
- Eu-central-1-waw-1a

14. Why cloud is cool?

15. - Cost saving
- Tourism industry during pandemic
- Unexpected traffic, scaling
- It’s fast to build apps (go global, time-to-market)
- Great services ready-to-use
- Opportunity to modernize/transform
- Backups automation
- On-prem services are hard to configure
Image source: https://www.avepoint.com/blog/migrate/sharepoint-online-migration-planning
Why companies migrate to cloud?

16. Why they choose AWS (or not)?
- It depends
- Business needs
- Proximity to DC - latency
- no.1 in Market Share
- Big number of AWS Partners/Experts
- Big number of available services
- Great success stories
https://www.reddit.com/r/orlybooks/comments/50meb5/it_depends/

17. Is cloud still hot in 2023?
- New services, market (and competition!) grows
- AWS - more than 200 services
- Great for learning - if you want to train and deploy some K8S / Terraform / ELK
- New trends:
- Cloud gaming
- Low code / no code solutions (AWS Honeycode)
- Multicloud
- Generative AI (Amazon Bedrock)
- Security as a Service (SECaaS) - continuous monitoring, vulnerability scanning, spam filtering
- Cloud became an important part of modern computing infrastructure
- Containerization, Kubernetes, IoT, Serverless, AI + Cloud

18. Biggest cloud concerns
- Cost optimization
- Cloud Security
- Misconfiguration!
- Outages
- Cloud expertise (Know your cloud, know its
limitation)
- “Reversed migrations”

19. AWS + Netflix
- Founded 1997
- Originally a DVD shipping business (red envelopes)
with 2 on-premises DCs
- 2008 - major outage that was lasting 3 days - they
were not able to ship out any DVDs
- Started migration (Aug 2008)
- Evolved quickly, they could not have racked the
servers to support their growth
- After seven years they switched of their last
physical DC (Jan 2016) - they rewrote apps in
cloud-native approach

20. AWS + Netflix now
- Responsible for 15% global internet traffic
(Sandvine 2023 Report)
- Youtube ~11,6%
- To analyze billions of messages across more than
100,000 application instances daily in real time
- More than 100,000 server instances on AWS
- Storage, computing, analytics, DBs,
recommendation engines, video transcoding

21. AWS + F1
- F1 is a data-driven sport
- With 300 sensors on each F1 race car generating
more than 1.1 million data points per second
transmitted from the cars to the pit
- With AWS, F1 has been able to turn millions of data
points transmitted from cars and trackside into an
engaging fan experience through its F1 Insights
- Predictions and Data Analysis
- Pit window, undercut threat, qualifying pace, tyre
performance

22. AWS + F1
- High-Performance Computing (HPC) to run
aerodynamic simulations
- With the use of these simulations - 2022 car design
- Downforce loss 50% -> 15%

via-design-of-experiments-and-machine-learning/

23. F1
- Magnetic, optical, laser-powered sensors
- Encrypted data is sent via radio frequency (antenna
mounted on the car)
- This isn’t just a radio frequency (Singapore, Baku) -
standardized communication network
- Pentesting, cybersecurity for data security
- Voice communication is not encrypted
- Mobile data centers/ at edge (different for each
team) that travels around the globe - PureStorage
for Mercedes
