What is Azure Big Data?
The Microsoft Azure cloud emphasizes AI and analytics services in its offering. This is a great option for those who want to combine the benefits of big data analytics with cloud computing. The Azure platform makes it easy to process structured and unstructured data in high volumes. It also comes with real-time analytics and a fully managed infrastructure that includes Azure database services, analytics services, machine learning and data engineering solutions.
In this article, you will learn:
- Big Data in Azure: Service Options
- Steps to Building a Big Data Solution on Azure
- Azure Big Data with NetApp Cloud Volumes ONTAP
Big Data in Azure: Use Cases
Azure provides a range of services that can help you set up a big data infrastructure, from databases, to data processing and analytics, to machine learning and integration of complex data sources.
Azure database options include self-managed Table Storage, self-managed databases hosted on a virtual machine, and managed databases such as SQL Server, PostgreSQL, MySQL, and MariaDB.
If you are interested in a fully managed service, you can use Cosmos DB by Azure. Cosmos is a scalable, flexible, low-latency service that supports global deployment and replication of multiple database engines. Its APIs are compatible with a wide range of tools, including MongoDB, Cassandra, Apache Spark, SQL, Jupyter Notebook, Table Storage, Gremlin, and more.
Azure also provides SQL Data Warehouse, for large scale structured data, and Azure Data Lake for unstructured data.
Azure provides a wide variety of analytics products and services. Currently, the most popular services are HDInsight and Azure Analysis Services.
Analysis Services provides an enterprise-class analysis engine that can collect data from multiple sources and turn it into an easy-to-use semantic BI model. The service integrates predefined database models and can generate interactive dashboards and reports. There’s no need for writing code or managing data processing.
Azure provides a variety of solutions for artificial intelligence and machine learning, including Azure Machine Learning Services (AMLS). AMLS lets you create customized machine learning models, using a zero-code drag and drop interface, as well as a code-first environment. It is compatible with open source tools and platforms such as PyTorch, TensorFlow, ONNX, and scikit-learn.
Azure Machine Learning Services helps automate machine learning with tools like automated feature selection, algorithm selection, and hyperparameter scanning.
There are two main Azure services you can use to create complex data pipelines: Data Factory and Data Catalog.
Data Factory provides serverless integration for local and cloud-based data repositories. You can use Data Factory to perform extract, load, transform (ELT) or extract, transform, load (ETL), using more than 80 data connectors provided natively by Azure. You can accomplish this with or without scripts. It can be automated with scheduling, drag and drop wizards, or event-based triggers. You can integrate Data Factory with Azure Monitor, to gain visibility and manage the performance of data flowing through CI/CD pipelines.
Data Catalog comes as a fully managed offering for finding and understanding data sources. With Data Catalog, you can crowdsource metadata and annotations to users and let them share their knowledge. This makes data more easily searchable and accessible.
Steps to Building a Big Data Solution on Azure
Microsoft recommends a three-step process to building a new big data solution in the Azure cloud: evaluation, architecture, configuration, and production.
Before choosing a service, you need to evaluate your big data goals. You must understand the type of data you want to include and how to format it. For example, data from web scraping is very different from the data you get from an IoT sensor. The type and amount of data used will help you plan data ingestion and the type of storage required.
Once you know what data to process, you must decide how to analyze it. If your team doesn't have a data scientist, you can use one of the big data service options. In this case, it is better to add machine learning to the system based on specific skills. Also take into account your current machine learning tools and scripting languages.
If you are new to cloud services, you should familiarize yourself with the full scope of an Azure migration. Consider starting your project by migrating core applications and processes to the cloud, and only then migrating your big data itself. It is possible to leverage the cloud for big data processing and analysis even without migrating large-scale datasets.
Suppose you want to create your own solution. Define an initial architecture based on the results of your evaluation. This architecture should depend on your legacy systems (if you have existing big data infrastructure in your local data center) and the skills of your development and operations teams. However, typical components of an architecture are shown below, and you can use them as a template for your individual setup.
After selecting the services, you need, you can configure and prepare your production environment. Your exact configuration will depend on the services you choose, the combination of data sources, and whether you are creating a hybrid or pure cloud environment.
Whatever specific configuration you use, you should monitor as many processes as possible to get the best performance and the best return on your investment. Azure Monitor and Log Analytics can be of help. Define and enforce a policy for privacy and security, and consider backup, restore, and disaster recovery for your big data system.
Azure Big Data with NetApp Cloud Volumes ONTAP
NetApp Cloud Volumes ONTAP, the leading enterprise-grade storage management solution, delivers secure, proven storage management services on AWS, Azure and Google Cloud. Cloud Volumes ONTAP supports up to a capacity of 368TB, and supports various use cases such as file services, databases, DevOps or any other enterprise workload, with a strong set of features including high availability, data protection, storage efficiencies, Kubernetes integration, and more.
In particular, Cloud Volumes ONTAP helps in addressing database workloads challenges in the cloud, and filling the gap between your Azure database capabilities and the Azure resources it runs on.
Cloud Volumes ONTAP supports advanced features for managing SAN storage in the cloud, catering for NoSQL database systems, as well as NFS shares that can be accessed directly from cloud big data analytics clusters.
In addition, the built-in storage efficiency features, including thin provisioning, data compression, deduplication, and data tiering, reduce storage footprint and costs by up to 70%.
