    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 need to compose visualization for operations teams with the following requirements:
    * Telemetry must include data from all 50,000 installations for the most recent 6 weeks (sampling once every minute)
    * The report must not be more than 3 hours delayed from live data.
    * The actionable report should only show suboptimal links.
    * Most suboptimal links should be sorted to the top.
    * Suboptimal links can be grouped and filtered by regional geography.
    * User response time to load the report must be <5 seconds.
    You create a data source to store the last 6 weeks of data, and create visualizations that allow viewers to see multiple date ranges, distinct geographic regions, and unique installation types. You always show the latest data without any changes to your visualizations. You want to avoid creating and updating new visualizations each month. What should you do?
  • Question 88

    You are choosing a NoSQL database to handle telemetry data submitted from millions of Internet-of-
    Things (IoT) devices. The volume of data is growing at 100 TB per year, and each data entry has about
    100 attributes. The data processing pipeline does not require atomicity, consistency, isolation, and
    durability (ACID). However, high availability and low latency are required.
    You need to analyze the data by querying against individual fields. Which three databases meet your
    requirements? (Choose three.)

    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.
