For organizations moving to cloud infrastructure, database migration can be the stuff of nightmares. When selecting a cloud-centric database, balancing ease of migration with the on-demand scaling and continuous availability your modern application needs can seem like a series of compromises... But it doesn’t have to be. In these slides, we showcase how simple it is to move from a traditional relational database to NuoDB’s elastic SQL database and talk about how this compares to the complexity of moving to a NoSQL database. Senior Product Manager Joe Leslie demonstrates how to use NuoDB’s built-in migrator facility to simplify migration from databases such as MySQL, Microsoft SQL Server, or Oracle over to NuoDB, minimizing the transition time, and making it easy to get started sooner.

Hinweis der Redaktion
- My name is… I’m joined by Tim Tadeo, a Solutions Architect with NuoDB. I’ll start by introducing the Elastic SQL database and why and how you should be thinking differently about databases as you move to a modern architecture. Tim will then do a live demonstration showing how to evaluate key aspects of an Elastic SQL database. I’ll wrap up with a pointer to resources available for you to conduct your own evaluation. At the end of the presentation we’ll be taking live questions from the audience. At any time during the webinar you can enter your questions using the Question box on the right side of your screen and we’ll address them at the end. We are also recording today’s webinar and will share the replay link with you should you wish to revisit it or share it with your colleagues. With that, let’s get started by exploring the database landscape
- To accomplish this, software organizations are rethinking everything about their computing environments - infrastructure, application development and operations. Data workloads are growing – everywhere – and storage and access for large datasets are a growing need as well Developers are a scare commodity Applications are being asked to do more and perform to more demanding requirements …while keeps costs to a minimum To accommodate these needs and transform in a service, customer-oriented business software orgs are moving their applications to the cloud As part of this modernization transformation, organizations must also consider how cloud applications will handle and store data
- Looking at the landscape today, we see that traditional relational databases are excellent at providing a business database of record with key capabilities around SQL and ACID properties, but as we’ve discussed, can’t scale out effectively. NoSQL technology can scale out elastically, but forgoes strict ACID compliance and full ANSI SQL support – making them less suitable for business-critical applications. Newer products – such as Google Cloud Platform Spanner, and CockroachDB promise the combination of these areas, with traditional relational designs that scale-out elastically. These first-generation products today provide limited SQL support making it harder to migrate existing SQL workloads to them, and rely on sophisticated clock synchronization limiting or constraining deployment flexibility. But they hold the promise of running business-critical applications in a cloud architecture. NuoDB, first introduced 4 years ago and proven in many production implementations, truly brings these worlds together with rich SQL support and ACID compliance in a scale-out architecture that can be deployed on-prem, across cloud providers, and even in a hybrid-cloud architecture.

- NuoDB has been built from the ground up to be an operational database that scales-out for cloud deployments. NuoDB appears as a single, logical, SQL database to the application, allowing developers to focus on building great applications, versus dealing with scale-out complexities. Under the hood, NuoDB has a peer-to-peer, two-layer, distributed architecture that can be deployed across multiple data centers and is optimized for in-memory speeds, continuous availability, and elastic scale-out. The transaction layer consists of in-memory process nodes called transaction engines (TE). Transaction engines handle requests from applications, cache data for fast access, and coordinate transactions with other process nodes in both the transaction and storage layers. As an application makes requests of NuoDB, the transaction engines will naturally build in-memory caches with affinity for that application’s data, allowing NuoDB to maintain high performance. The storage layer consists of process nodes called storage managers (SM). The storage manager ensures durability of data by writing it to disk, manages data on disk, handles requests from transaction engines (TEs), and sends asynchronous messages to other SMs to commit data to disk and to maintain copies of data in memory. These process nodes provide ACID-guarantees, data redundancy, and data persistence. Within both layers, NuoDB can elastically scale out (and back) without any interruption to application service, simply by adding and removing TEs and SMs. This means developers can design applications to access a single logical database and not worry about handling scale out complexity related to dynamic operational workloads. Database operators can scale out the database to accommodate dynamic workloads and not worry about adverse consequences to the application. The result is that developers and operations can focus on truly maximizing performance of both the application and the database.
