Migrating on-premises data to the Azure cloud involves several steps to ensure a smooth and secure transition. Here’s a step-by-step guide on how to move your data from on-premises to Azure: 1. Assess and Plan Your Data Migration Data Inventory: Identify the data types, sizes, and storage formats you want to migrate. Data Sensitivity: Classify data based on sensitivity (e.g., confidential, public) to apply appropriate security measures. Network Bandwidth: Evaluate your network capacity to determine how much data can be moved over the network at a time. Migration Strategy: Choose between: Offline Transfer: For large datasets (terabytes to petabytes), use Azure Data Box. Online Transfer: Use tools like AzCopy, Azure Data Factory, or Azure Migrate for continuous data replication and migration over the internet. 2. Choose the Right Azure Storage Service Azure Blob Storage: Ideal for unstructured data like images, videos, and backups. Azure Files: Suitable for file shares and network file system (NFS) access. Azure SQL Database: For structured data from SQL Server, Oracle, etc. Azure Cosmos DB: If you need a globally distributed, NoSQL database. 3. Prepare Your Azure Environment Create Azure Storage Accounts: Set up appropriate Azure storage accounts (Blob, File, SQL) depending on your data types. Network Configuration: Use Azure ExpressRoute for faster data transfer via a private network connection or VPN Gateway for secure internet-based transfer. 4. Migrate the Data Method 1: Using Azure Data Factory (Online) Azure Data Factory (ADF): This is an orchestration service that allows you to move and transform data. Create a new Data Factory in the Azure portal. Configure a data pipeline to connect to your on-premises data source using self-hosted integration runtime. Choose the destination in Azure (Blob Storage, Data Lake, or SQL Database). Schedule and run the pipeline to start migrating data. Method 2: Using AzCopy (Online) AzCopy: A command-line tool to copy data to Azure. Download and install AzCopy. Authenticate using Azure AD or a shared access signature (SAS) token. Use the command to upload files: Method 3: Using Azure Data Box (Offline) Azure Data Box: A physical appliance provided by Microsoft to ship large amounts of data offline. Order the Azure Data Box from the Azure portal. Copy the on-prem data to the Data Box. Ship the Data Box to Microsoft, where they will upload the data to your Azure storage account. Validate the data in your Azure environment. Method 4: SQL Data Migration Azure Database Migration Service (DMS): Used to migrate SQL and other relational databases. Set up a migration project in DMS. Connect your on-premises database (e.g., SQL Server) and choose Azure SQL as the target. Choose either online migration (with continuous replication) or offline migration (one-time transfer). Migrate the data and validate once the process completes.

I was unaware until today that DynamoDB can be used for storing transactional data, as it supports ACID properties needed in a typical transactional database. What makes DynamoDB fascinating is its serverless nature (which means we don’t have to worry at all about managing the infrastructure or scaling, AWS handles that automatically) and its performant capabilities, which are again offered out of the box by AWS itself. I knew MongoDB was one of the best NoSQL databases for supporting ACID transactions, but I always had an understanding that DynamoDB was one of those databases that could only store document-related content and I was wrong. DynamoDB is much more than that! Interestingly, Grab uses DynamoDB to store and process millions of orders daily.

Lately, I've been thinking about how to choose the right database or how to even recommend a database solution to customers. There are so many choices out there, that it made me wonder what considerations really needed to be accounted for. Not to mention, choosing the right database can make or break a project or an organization. But with so many options—SQL, NoSQL, NewSQL, and others—how do you decide? In my latest article on Dev.to, I break down the types of databases, their use cases, and how to choose between on-premises and cloud solutions. I think developers, solutions architects, and data enthusiasts will find this guide helpful for making informed decisions. Let me know your thoughts or experiences in the comments!

Customers of every business want assurance that, when they seek information or services from enterprises, they can base their decisions on data that’s relevant, readily available, and secure. This assurance comes from the database. A secure, highly performant database available globally forms the foundation for AI-driven applications. “Now that Oracle Database supports even more data types and development paradigms, developers have more opportunities to solve a wide range of problems with one unified, powerful approach,”? #OCI #ADB #AI #Data #AWS #Azure #GCP
