Oracle Exadata and Apache Hadoop compete in high-performance data processing solutions. Oracle Exadata has the upper hand in database-centric tasks, particularly for OLTP applications, while Apache Hadoop stands out in managing large volumes of unstructured data.
Features: Oracle Exadata offers high-performance data processing with automatic tuning and component integration, making it suitable for data warehousing and OLTP applications. It features Smart Scan and Hybrid Columnar Compression for faster data processing and compression, alongside its capability for smart flash cache. Apache Hadoop excels in scalability and handling large volumes of unstructured data, utilizing HDFS for flexible storage and Impala for quick SQL query execution.
Room for Improvement: Oracle Exadata struggles with high licensing costs, making it less viable for small-scale operations. It is tied to Oracle software, reducing flexibility. Apache Hadoop, although cost-effective, has challenges in data replication and complex setup procedures, with users seeking better integration and simpler installation processes.
Ease of Deployment and Customer Service: Oracle Exadata is largely deployed on-premises, with positive reviews on Oracle's support but criticisms over slow resolution times and expensive maintenance. Users report the need for streamlined support processes for complex issues. Apache Hadoop is mainly utilized in cloud environments, offering cost benefits from its open-source nature but demands specialized expertise for effective usage. Support can vary, with requests for stronger community assistance and documentation.
Pricing and ROI: Oracle Exadata is viewed as expensive and is more suitable for larger enterprises due to its database licensing models that can offer long-term savings. Despite its high initial cost, the performance and stability may provide a good ROI. Apache Hadoop, being open-source, is generally more budget-friendly, though costs might arise based on specific distributions or cloud usage, offering efficiency in processing substantial datasets.
The investment is good, which is why people choose this hardware.
Exadata comes with a platinum gateway and comprehensive support, which often gets immediate attention with severity one cases.
Within a site, scalability is excellent.
Once installed, Exadata is very stable.
I cannot create an extended rack cluster with one node on one site and another node on a different site.
It also offers high backend speed between self-storage units and servers, which is beneficial for processing.
Oracle Exadata allows enterprises to run any Oracle Database workload with the highest performance, scale, availability, and security on fully compatible cloud and on-premises infrastructure. Exadata uses a scale-out design with unique optimizations that include persistent memory, SQL query offload, and built-in resource management to optimize performance for OLTP, analytics, machine learning, and mixed workloads running in consolidated environments. By running hundreds or thousands of optimized Autonomous Database and Exadata Database instances on Exadata Cloud or Cloud@Customer infrastructure, customers are able to minimize their infrastructure, reduce management, improve developer productivity, and lower total costs by up to 40%, as described in Wikibon’s analysis (PDF).
The main benefit of Exadata is its speed. It hosts operating systems, CPU memory, and hard drives. It runs all types of databases, including online transaction systems, processors, and data warehouses, while remedying the poor performances of older databases.
Oracle Exadata features a simple and fast database storage system that protects and backs up your critical data. It accelerates data warehouse performance for faster access to business information and data. It is the ideal database solution for companies looking to build up their infrastructure from scratch.
Oracle Exadata Database Machine Key Benefits
Accelerate database processing: Exadata Storage Server implements a unique, highly efficient database-optimized storage infrastructure that enables Exadata’s unparalleled performance without any of the bottlenecks that traditional storage experiences. Each storage server contains CPU processors that are used to offload database processing. The CPUs in the storage servers do not replace database CPUs, but work alongside them to accelerate database workloads.
Reviews from Real Users
Oracle Exadata stands out among its competitors for a number of reasons. Two major ones are its robust performance and its wide variety of database features that make it a comprehensive database solution.
Adriano S., an IT system integrator at a financial services firm, writes, "Oracle Exadata's performance is one of its best features. We are very satisfied with it. The previous equipment used to make a payment for all the government employees used to take at least two days for some of the transactions. Now, it will take hours to make the same amount of payments. Another thing is the flexibility to organize all our databases. We can use it with new features that come with this version of Oracle 19c, which is the container database. With container databases, we can work with many databases, organized, and segregated, and still access the functions and management, the things that most of the technical people like to have in place."
Paulo X., a sales manager at LTA-RH Informatica, notes, "Regarding features, there are so many that we can offer to customers. When we sell Exadata Cloud, there are many options to choose from, especially when it comes to enterprise database options. In my experience, the main features that are appreciated are various ones like GPS and the assortment of security options."
