Plan, Costs, Tools, and Best Practices
In big data services since 2013, ScienceSoft designs, develops, and supports secure and scalable Hadoop-based apps that drive high ROI and successfully handle quickly growing volumes of data.
Hadoop Implementation In a Nutshell
Hadoop implementation is a crucial first step to building powerful big data solutions capable of processing massive datasets and driving advanced analytics. Adopted by such global market giants as Facebook, eBay, Uber, Netflix, and LinkedIn, Hadoop-based apps help handle petabytes of data from various sources and derive strategically vital insights from it.
Key big data implementation steps: feasibility study, requirements engineering, software conceptualization and planning, architecture design, Hadoop implementation and testing, deployment, support and maintenance.
Team: project manager, business analyst, big data architect, Hadoop developers, data engineer, data scientist, data analyst, DataOps engineer, DevOps engineer, QA engineer, test engineers.
Costs: from $50K to $2+M, depending on the project scope.
With extensive hands-on experience in big data, ScienceSoft designs and implements secure and scalable Hadoop-based solutions for 30+ industries, including BFSI, healthcare, retail, manufacturing, education, telecoms, and more.
Hadoop may be used as a base for a large variety of components (e.g., Hive, HBase, Spark, etc.) to meet different purposes. So, its implementation roadmap naturally alters depending on the solution requirements. Still, based on ScienceSoft’s experience, there are six high-level steps that are common for most Hadoop projects:
- Analyzing your business needs and goals, outlining the current data handling issues (e.g., low system performance due to increased volume of heterogeneous data, data quality management challenges).
- Evaluating the viability of implementing a Hadoop-based app, calculating the approximate ROI and future operational costs for the solution-to-be.
- Eliciting functional and non-functional requirements for the Hadoop solution, including the relevant compliance requirements (e.g., HIPAA, PCI DSS, GDPR).
- Identifying the required data sources with regard to the data type, volume, structure, etc. Deciding on target data quality thresholds (e.g., data consistency, completeness, accuracy, auditability).
- Deciding on the data processing approach (batch, real-time, both).
- Defining the needed integrations with the existing apps and IT infrastructure components.
Solution conceptualization and planning
- Defining the key logical components of the future app (e.g., a data lake, batch and/or real-time processing, a data warehouse, analytics and reporting modules).
- Estimating the required size and structure of Hadoop clusters, taking into account:
- The volume of data to be ingested by Hadoop.
- The expected data flow growth.
- Replication factor (e.g., for an HDFS cluster it’s 3 by default).
- Compression rate (if applicable).
- The space reserved for OS activities.
- Choosing the deployment model (on-premises, cloud, hybrid).
- Selecting the best suited technology stack.
- Preparing a detailed project plan, including the project schedule, required skills, budget, etc.
To help our customers choose the most cost-efficient deployment model, ScienceSoft focuses on the key priorities of the project.
We usually recommend deploying Hadoop in the cloud if application elasticity is needed and the requirements for the computing resources are likely to change in the future (e.g., you may need more storage or processing power). That’s the case for the majority of Hadoop-based apps, so cloud deployment is our go-to option.
Going for on-premises deployment is feasible if harsh security requirements are to be met, the project scope is unlikely to change, and the customer is ready to invest in hardware, office space, DevOps team ramp-up, etc.
- Creating a high-level scheme of the future solution with the key data objects, their connections, and major data flows.
- Working out the data quality management strategy.
- Planning the data security measures (encryption of data at rest and in motion, data masking, user authentication, fine-grained user access control).
- Designing a scalable solution architecture that contains at least four major layers:
- Distributed data storage layer represented by HDFS (Hadoop Distributed File System). As the name suggests, HDFS divides large incoming files into manageable data blocks and replicates each dataset at least 3 times to store them across several nodes, or computers. This way, data is protected against loss in case of a node failure. Among HDFS’s alternatives offered by cloud providers are Amazon S3 and Azure Blob Storage.
- Resource management layer consisting of YARN that serves as an OS to a Hadoop-based solution. YARN ensures balanced resource loading by scheduling the data processing jobs. If supplemented with Apache Spark or Storm, YARN can help enable stream data processing.
- Data processing layer with MapReduce at its core that splits input data to be processed in parallel as individual units. The processed datasets are then sorted out and aggregated as a final output ready for querying. Nowadays, data processing is often conducted with the help of additional tools, such as Apache Hive, Pig, and other tools depending on the specific solution’s needs.
- Data presentation layer (usually represented by Hive and/or HBase) that provides quick access to the data stored in Hadoop, enabling data querying and further analysis.
In real-life Hadoop-based apps, Hadoop techs are most often combined with other big data frameworks (e.g., Apache Spark, Storm, Kafka, Flink) to achieve the desired functionality.
Hadoop implementation and testing
- Setting up the environments for development and delivery automation (СI/CD pipelines, container orchestration, etc.).
- Building the Hadoop-based app using the selected techs and implementing the planned data security measures.
- Establishing QA processes in parallel with the development. Conducting comprehensive testing, including functional testing (validating the app’s business logic, continuous data availability, report generation, etc.), performance, security, and compliance testing.
Hadoop-based app deployment
- Running pre-launch user acceptance tests to confirm that the solution performs well in real-world scenarios.
- Launching the application in the production environment, establishing the required security controls (access permissions, logging mechanisms, encryption key management, patching automation, etc.).
- Choosing and configuring the monitoring tools to track the computing resources capacity and usage, performance, connectivity, DataNode health, etc.
- Starting data ingestion from real-life data sources, ensuring that the target data quality thresholds are achieved.
- Conducting user training.
After-launch support and evolution (continuous)
- Setting the support and maintenance procedures to ensure the smooth operation of the solution: addressing user and system issues, optimizing the usage of computing and storage resources, etc.
- Adjusting the solution to the evolving business needs: adding new functional modules and integrations, implementing new security measures, etc.
