The document compares traditional on-premises IT models with cloud computing, highlighting the agility and cost-effectiveness of cloud solutions like AWS. It emphasizes the shift towards serverless architectures that enable rapid deployment, scalability, and reduced operational costs. Companies adopting cloud technologies can innovate quicker and focus on core business logic rather than infrastructure management.

1. The Cloud: What’s Different?

2. Today’s Section
• Contrast the AWS Cloud to traditional on-premises model.
• Serverless: The New Cloud Trend
• Q&A

3. 14 YEARS
70%
66%
New Trends On The S&P 500
The average tenure of companies is forecast to
shrink to 14 years by 2026 from 20 years by 1990.
IT Budgets : 70% for Run Business, 20% for Grow
Business, only 10% for Transform Business.
66% planning to increase IT security budgets as a
direct response to this risk.

4. What The Meaning of Number?
The traditional model of enterprises lacks agility
and cannot keep pace with new companies.
Lack of the resources to meet new business
needs to ensure competitive advantage.
Safety, compliance, and lack of usability have
reduced the competitiveness and put into risk.

9. The Facing Problems
• Hiring a group of people or buying equipment
unrelated to core business development.
• It is difficult to estimate the IT budget.
• Lack of flexibility in adjusting resources.
• Build own wheels that belong to the company.
The company loses competitiveness

10. How Companies Succeed
Innovation or adopting new technologies to
"incremental" improvement over time.
Minimum viable product and faster of delivery
speed to reached the target market.
Scalability of IT infrastructure for expansion and
reduction for response to the business cost.

11. Cloud Computing
A simple way to access servers, storage, databases and a
broad set of application services over the Internet.

20. The Traditional VS Cloud Computing
Traditional
• Massive Up-front cost, Big “Steps”
• IT Staff focus on the data center
• In-house knowledge limits
• Recreate the wheel
• It’s yours
• “Monster server” capability
Cloud
• Pay as you go, Pricing Models
• Elastic Computing, Grow as needed
• Economy of scale
• Immediate security accreditation
• Globalize Infrastructure
• Collaborative Innovation
• Horizontal Scaling

32. Server to Serverless
Application and
Operation teams design,
acquire, and maintain
servers to meet the
specific needs of
application.
Hardware abstracted
away to allow for
specific CPU, Memory,
Storage, and Network to
meet the needs of
application on a per
server basis.
Hardware and Operating
System is abstracted
away. Can packaged to
run in resource-isolated
processes.
Applications are built
using a combination of
services. Break
application into small
bite sized pieces.

37. Programming Language Support
• JavaScript with Node.js
• Java
• Python
• C# with .NET Core
https://docs.aws.amazon.com/lambda/latest/dg/current-supported-versions.html

38. Pay per request
• Buy compute time in 100ms increments.
• Low request charge.
• No hourly, daily or monthly minimums.
• Only pay for running, never pay for idle.
Free tier: 1 million requests, and 400,000 GBs of compute
every month for every customer.

43. Case Study

44. Background
As a Customer
I want a New Service that can auto-generate daily summary report
according to the display from current back-end system(web), and
send this report to related people
So that we can do the Marketing Analysis more accurately.

45. Todo List
• Make a Crawler to gathering information from system display.
• Design a mechanism to convert the information and generate
daily report.
• Integrate File System for report stored.
• Integrate Mail Service to send the report.
• Design the system high-availability and scalability.

46. Traditional Architecture
Buying Server and setup environment for 2 weeks.
Programing development
- 1 weeks for service setup(file server, email, web
server)
- 1 weeks for core functions
- 2 weeks for high availability and scalability.
Difficult to estimate Cost and Capacity. And Lost the
Focus on development.

49. Results
• Delivery from 6 weeks reduce to 1 week.
• Save 90% cost in the front of the project and has
predictable billing report for evaluating.
• Enable fully Auto-scaling and High-availability.
• Report file been Protecting from AWS S3.
• 1 command to deploy and delivery in seconds.
