虽然考试的时候会让你看案例，但是由于时间关系，所以建议提前看了。此外还有，对于这个案例，我在网上搜到有人专门分析的，所以把地址也贴在下面，也建议大家一起看看，这个很重要。
case studies
Sample1 - Dress4Win Case Study
Company Overview
Dress4Win is a web-based company that helps their users organize and manage their personal wardrobe
using a web app and mobile application. The company also cultivates an active social network that
connects their users with designers and retailers. They monetize their services through advertising,
ecommerce, referrals, and a freemium app model. The application has grown from a few servers in the
founder’s garage to several hundred servers and appliances in a colocated data center. However, the
capacity of their infrastructure is now insufficient for the application’s rapid growth. Because of this growth
and the company’s desire to innovate faster, Dress4Win is committing to a full migration to a public cloud.
Solution Concept
For the first phase of their migration to the cloud, Dress4Win is moving their development and test
environments. They are also building a disaster recovery site, because their current infrastructure is at a
single location. They are not sure which components of their architecture they can migrate as is and
which components they need to change before migrating them.
Existing Technical Environment
The Dress4Win application is served out of a single data center location. All servers run Ubuntu LTS
v16.04.
- Databases:
● MySQL. One server for user data, inventory, static data
○ MySQL 5.7
○ 8 core CPUs
○ 128 GB of RAM
○ 2x 5 TB HDD (RAID 1)
- Compute:
● 40 web application servers providing micro-services based APIs and static content
○ Tomcat - Java
○ Nginx
○ Four core CPUs
○ 32 GB of RAM
● 20 Apache Hadoop/Spark servers:
○ Data analysis
○ Real-time trending calculations
○ Eight core CPUs
○ 128 GB of RAM
○ 4x 5 TB HDD (RAID 1)
● Three RabbitMQ servers for messaging, social notifications, and events
○ Eight core CPUs
○ 32GB of RAM
● Miscellaneous servers:
○ Jenkins, monitoring, bastion hosts, security scanners
○ Eight core CPUs
○ 32GB of RAM
Storage appliances:
● iSCSI for VM hosts
● Fibre channel SAN - MySQL databases
○ 1 PB total storage; 400 TB available
● NAS - image storage, logs, backups
○ 100 TB total storage; 35 TB available
Business Requirements
● Build a reliable and reproducible environment with scaled parity of production
● Improve security by defining and adhering to a set of security and identity and access
management (IAM) best practices for cloud
● Improve business agility and speed of innovation through rapid provisioning of new resources
● Analyze and optimize architecture for performance in the cloud
Technical Requirements
● Easily create non-production environments in the cloud
● Implement an automation framework for provisioning resources in cloud
● Implement a continuous deployment process for deploying applications to the on-premises data
center or cloud
● Support failover of the production environment to cloud during an emergency
● Encrypt data on the wire and at rest
● Support multiple private connections between the production data center and cloud environment.
Executive Statement
Our investors are concerned about our ability to scale and contain costs with our current infrastructure.
They are also concerned that a competitor could use a public cloud platform to offset their up-front investment and free them to focus on developing better features. Our traffic patterns are highest in the mornings and weekend evenings; during other times, 80% of our capacity is sitting idle[闲置].
Our capital expenditure[资本支出] is now exceeding our quarterly projections. Migrating to the cloud will likely cause an initial increase in spending, but we expect to fully transition before our next hardware refresh cycle.
Our total cost of ownership (TCO)[拥有成本由购买成本，操作成本，维护成本三方面构成] analysis over the next five years for a public cloud strategy achieves a cost reduction between 30% and 50% over our current model.
