1. Introducing Managed Cassandra Apache Cassandra is an open source, distributed database. Its masterless, shared-nothing architecture provides operational database applications with near-constant uptime and simple, linear scalability. Cassandra provides for a flexible data model capable of storing modern datatypes structured, semi-structured and unstructured that run through today s web/mobile applications. However, while Cassandra s masterless architecture makes it easy to maintain at first, ensuring optimal performance becomes increasingly complex as you scale, and soon requires costly expertise that is often difficult and time-consuming to find and retain. In many cases, developers spend too much time maintaining and troubleshooting the database layer, which distracts them from writing code. Managed Cassandra is a production-ready database service built on the award-winning DataStax Enterprise (DSE) platform that frees developers to focus on building innovative apps. It simplifies database management by offering pre-configured, fully managed, highly performant, highly available Cassandra instances, backed by industryleading Fanatical Support 24x7x365. By combining purpose-built technology with leading expertise, the Managed Cassandra platform offers: 1. Simplified management 2. Bare-metal performance 3. Highly available, production-ready instances 4. Easy, powerful scalability DSE IS BUILT FOR THE ENTERPRISE WITH THE FOLLOWING FEATURES: Production-certified Cassandra with full software lifecycle management Comprehensive enterprise security Automatic management services for transparent maintenance operations Built-in enterprise search capabilities on Cassandra data Integrated streaming, real-time, batch analytics, and Hadoop integration Workload management for transactional, analytic and search operations In-memory option for lightning-fast transactional and analytics workloads 5. Data and application portability Managed Cassandra is ideal for businesses that need the scalability, flexibility and availability of NoSQL to power innovative web, mobile or internet-of-things (IoT) apps, but that also need: The reliability of a production-ready solution Fast time-to-market provided by a turn-key solution Freedom to have their developers focus on coding and their IT focus on innovating, rather than on maintenance and tuning at the database layer.

2. Challenges of Managing Cassandra It s easy for many developers to start building applications with Cassandra. And because all nodes in a cluster are the same, there are no complex software tiers to manage. This makes maintenance relatively simple at first. However, maintaining performance and ensuring high availability present a range of challenges as your environment grows. NEXT-GEN APPS PLACE NEW DEMANDS ON DATABASES Web and mobile apps have new availability and scalability demands that traditional database technologies aren t always well suited for. Cassandra s distributed, always-on architecture is ideal for many of these use cases. However, as we know from the hundreds of large, innovative companies that use it to power their modern applications, enterprises require the reliability of a production-ready solution to ensure that Cassandra is (1) quick to deploy, (2) able to meet their availability and security requirements, and (3) properly architected to achieve significant scale. MANAGING CASSANDRA STRAINS EXISTING TECHNICAL RESOURCES Many businesses that choose Cassandra find that their developers are spending too much time tuning, patching, monitoring and troubleshooting database performance and rethinking configuration decisions as opposed to writing code. This can slow time-to-market, decrease application quality, and deprive technical contributors of the time they need to pursue new ideas. EXPERTISE IS SCARCE AND EXPENSIVE Because Cassandra is a relatively new technology, it s often both difficult and expensive to find, hire and retain employees with a proven track record of managing it in large production environments. This not only puts additional pressure on existing resources, but can also create a host of other complexities including scaling, maintaining, securing and optimizing Cassandra beyond the initial configuration requiring specialized expertise. CONFIGURATION AND TUNING MISSTEPS IMPACT PERFORMANCE With Cassandra, there are many index design and configuration options that require specific expertise in order to optimize for performance. Mistakes can result in slower-than-desired performance or downtime, which detract from Cassandra s primary value proposition (i.e. a highly available, scalable database that doesn t compromise performance). For instance, Cassandra is written in Java. While more recent versions of Cassandra have strived to eliminate the need to tune the notoriously difficult Java Virtual Machine (JVM), some JVM tuning is still required for certain workloads. Failure to do so can result in increased latency or even failure. Fully Managed, High-performance Cassandra Service Page 2
