7. Topic 4, Dress4Win case study



Company Overview

Dress4win is a web-based company that helps their users organize and manage their personal wardrobe using a website 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, e-commerce, referrals, and a premium app model.



Company Background

Dress4win’s application has grown from a few servers in the founder’s garage to several hundred servers and appliances in a collocated 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 considering moving their development and test environments. They are also considering 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.

- Databases:

- MySQL - user data, inventory, static data

- Redis - metadata, social graph, caching

- Application servers:

- Tomcat - Java micro-services

- Nginx - static content

- Apache Beam - Batch processing

- Storage appliances:

- iSCSI for VM hosts

- Fiber channel SAN - MySQL databases

- NAS - image storage, logs, backups

- Apache Hadoop/Spark servers:

- Data analysis

- Real-time trending calculations

- MQ servers:

- Messaging

- Social notifications

- Events

- Miscellaneous servers:

- Jenkins, monitoring, bastion hosts, security scanners



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.

- Migrate fully to the cloud if all other requirements are met.



Technical Requirements

- Evaluate and choose an automation framework for provisioning resources in cloud.

- Support failover of the production environment to cloud during an emergency.

- Identify production services that can migrate to cloud to save capacity.

- Use managed services whenever possible.

- Encrypt data on the wire and at rest.

- Support multiple VPN connections between the production data center and cloud environment.



CEO Statement

Our investors are concerned about our ability to scale and contain costs with our current infrastructure. They are also concerned that a new competitor could use a public cloud platform to offset their up-front investment and freeing them to focus on developing better features.



CTO Statement

We have invested heavily in the current infrastructure, but much of the equipment is approaching the end of its useful life. We are consistently waiting weeks for new gear to be racked before we can start new projects. Our traffic patterns are highest in the mornings and weekend evenings; during other times, 80% of our capacity is sitting idle.



CFO Statement

Our capital expenditure 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) analysis over the next 5 years puts a cloud strategy between 30 to 50% lower than our current model.



The current Dress4win system architecture has high latency to some customers because it is located in one data center.

As of a future evaluation and optimizing for performance in the cloud, Dresss4win wants to distribute it's system architecture to multiple locations when Google cloud platform.

Which approach should they use?

8. Your development team has installed a new Linux kernel module on the batch servers in Google Compute Engine (GCE) virtual machines (VMs) to speed up the nightly batch process. Two days after the installation, 50% of web application deployed in the same

nightly batch run. You want to collect details on the failure to pass back to the development team .

9. For this question, refer to the Mountkirk Games case study.

Mountkirk Games' gaming servers are not automatically scaling properly. Last month, they rolled out a new feature, which suddenly became very popular. A record number of users are trying to use the service, but many of them are getting 503 errors and very slow response times .

What should they investigate first?

10. One of the developers on your team deployed their application in Google Container Engine with the Dockerfile below.

What is the Google recommended tool for such applications?

17. For this question, refer to the TerramEarth case study.

TerramEarth plans to connect all 20 million vehicles in the field to the cloud. This increases the volume to 20 million 600 byte records a second for 40 TB an hour .

How should you design the data ingestion?

18. You are developing an application using different microservices that should remain internal to the cluster. You want to be able to configure each microservice with a specific number of replicas. You also want to be able to address a specific microservice from any other microservice in a uniform way, regardless of the number of replicas the microservice scales to. You need to implement this solution on Google Kubernetes Engine .

What should you do?

19. Migrate all virtual machines into Compute Engine.

20. For this question, refer to the TerramEarth case study.

To speed up data retrieval, more vehicles will be upgraded to cellular connections and be able to transmit data to the ETL process. The current FTP process is error-prone and restarts the data transfer from the start of the file when connections fail, which happens often. You want to improve the reliability of the solution and minimize data transfer time on the cellular connections .

As part of Dress4Win's plans to migrate to the cloud, they want to be able to set up a managed logging and monitoring system so they can handle spikes in their traffic load. They want to ensure that:

• The infrastructure can be notified when it needs to scale up and down to handle the ebb and flow of usage throughout the day

• Their administrators are notified automatically when their application reports errors.

• They can filter their aggregated logs down in order to debug one piece of the application across many hosts
