    MJTelco Case Study
    Company Overview
    MJTelco is a startup that plans to build networks in rapidly growing, underserved markets around the world.
    The company has patents for innovative optical communications hardware. Based on these patents, they can create many reliable, high-speed backbone links with inexpensive hardware.
    Company Background
    Founded by experienced telecom executives, MJTelco uses technologies originally developed to overcome communications challenges in space. Fundamental to their operation, they need to create a distributed data infrastructure that drives real-time analysis and incorporates machine learning to continuously optimize their topologies. Because their hardware is inexpensive, they plan to overdeploy the network allowing them to account for the impact of dynamic regional politics on location availability and cost.
    Their management and operations teams are situated all around the globe creating many-to-many relationship between data consumers and provides in their system. After careful consideration, they decided public cloud is the perfect environment to support their needs.
    Solution Concept
    MJTelco is running a successful proof-of-concept (PoC) project in its labs. They have two primary needs:
    * Scale and harden their PoC to support significantly more data flows generated when they ramp to more than 50,000 installations.
    * Refine their machine-learning cycles to verify and improve the dynamic models they use to control topology definition.
    MJTelco will also use three separate operating environments - development/test, staging, and production - to meet the needs of running experiments, deploying new features, and serving production customers.
    Business Requirements
    * Scale up their production environment with minimal cost, instantiating resources when and where needed in an unpredictable, distributed telecom user community.
    * Ensure security of their proprietary data to protect their leading-edge machine learning and analysis.
    * Provide reliable and timely access to data for analysis from distributed research workers
    * Maintain isolated environments that support rapid iteration of their machine-learning models without affecting their customers.
    Technical Requirements
    Ensure secure and efficient transport and storage of telemetry data
    Rapidly scale instances to support between 10,000 and 100,000 data providers with multiple flows each.
    Allow analysis and presentation against data tables tracking up to 2 years of data storing approximately 100m records/day Support rapid iteration of monitoring infrastructure focused on awareness of data pipeline problems both in telemetry flows and in production learning cycles.
    CEO Statement
    Our business model relies on our patents, analytics and dynamic machine learning. Our inexpensive hardware is organized to be highly reliable, which gives us cost advantages. We need to quickly stabilize our large distributed data pipelines to meet our reliability and capacity commitments.
    CTO Statement
    Our public cloud services must operate as advertised. We need resources that scale and keep our data secure.
    We also need environments in which our data scientists can carefully study and quickly adapt our models.
    Because we rely on automation to process our data, we also need our development and test environments to work as we iterate.
    CFO Statement
    The project is too large for us to maintain the hardware and software required for the data and analysis. Also, we cannot afford to staff an operations team to monitor so many data feeds, so we will rely on automation and infrastructure. Google Cloud's machine learning will allow our quantitative researchers to work on our high-value problems instead of problems with our data pipelines.
    You create a new report for your large team in Google Data Studio 360. The report uses Google BigQuery as its data source. It is company policy to ensure employees can view only the data associated with their region, so you create and populate a table for each region. You need to enforce the regional access policy to the data.
    Which two actions should you take? (Choose two.)

    Flowlogistic Case Study
    Company Overview
    Flowlogistic is a leading logistics and supply chain provider. They help businesses throughout the world manage their resources and transport them to their final destination. The company has grown rapidly, expanding their offerings to include rail, truck, aircraft, and oceanic shipping.
    Company Background
    The company started as a regional trucking company, and then expanded into other logistics market. Because they have not updated their infrastructure, managing and tracking orders and shipments has become a bottleneck. To improve operations, Flowlogistic developed proprietary technology for tracking shipments in real time at the parcel level. However, they are unable to deploy it because their technology stack, based on Apache Kafka, cannot support the processing volume. In addition, Flowlogistic wants to further analyze their orders and shipments to determine how best to deploy their resources.
    Solution Concept
    Flowlogistic wants to implement two concepts using the cloud:
    * Use their proprietary technology in a real-time inventory-tracking system that indicates the location of their loads
    * Perform analytics on all their orders and shipment logs, which contain both structured and unstructured data, to determine how best to deploy resources, which markets to expand info. They also want to use predictive analytics to learn earlier when a shipment will be delayed.
    Existing Technical Environment
    Flowlogistic architecture resides in a single data center:
    * Databases
    * 8 physical servers in 2 clusters
    * SQL Server - user data, inventory, static data
    * 3 physical servers
    * Cassandra - metadata, tracking messages
    10 Kafka servers - tracking message aggregation and batch insert
    * Application servers - customer front end, middleware for order/customs
    * 60 virtual machines across 20 physical servers
    * Tomcat - Java services
    * Nginx - static content
    * Batch servers
    Storage appliances
    * iSCSI for virtual machine (VM) hosts
    * Fibre Channel storage area network (FC SAN) - SQL server storage
    * Network-attached storage (NAS) image storage, logs, backups
    * 10 Apache Hadoop /Spark servers
    * Core Data Lake
    * Data analysis workloads
    * 20 miscellaneous servers
    * Jenkins, monitoring, bastion hosts,
    Business Requirements
    * Build a reliable and reproducible environment with scaled panty of production.
    * Aggregate data in a centralized Data Lake for analysis
    * Use historical data to perform predictive analytics on future shipments
    * Accurately track every shipment worldwide using proprietary technology
    * 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
    * Handle both streaming and batch data
    * Migrate existing Hadoop workloads
    * Ensure architecture is scalable and elastic to meet the changing demands of the company.
    * Use managed services whenever possible
    * Encrypt data flight and at rest
    * Connect a VPN between the production data center and cloud environment SEO Statement We have grown so quickly that our inability to upgrade our infrastructure is really hampering further growth and efficiency. We are efficient at moving shipments around the world, but we are inefficient at moving data around.
    We need to organize our information so we can more easily understand where our customers are and what they are shipping.
    CTO Statement
    IT has never been a priority for us, so as our data has grown, we have not invested enough in our technology. I have a good staff to manage IT, but they are so busy managing our infrastructure that I cannot get them to do the things that really matter, such as organizing our data, building the analytics, and figuring out how to implement the CFO' s tracking technology.
    CFO Statement
    Part of our competitive advantage is that we penalize ourselves for late shipments and deliveries. Knowing where out shipments are at all times has a direct correlation to our bottom line and profitability. Additionally, I don't want to commit capital to building out a server environment.
    Flowlogistic wants to use Google BigQuery as their primary analysis system, but they still have Apache Hadoop and Spark workloads that they cannot move to BigQuery. Flowlogistic does not know how to store the data that is common to both workloads. What should they do?
