What is the primary goal of oracle maximum availability architecture for customer systems?
On Prime Day of 2018, July 16,
Amazon lost an estimated $72 million to $99 million due to little over hour-long connection issues faced by the customers. Despite the downtime, Amazon anyway went on to earn $3.4 billion worth of sales, but then, they are the World’s biggest business enterprise.

For enterprises aspiring to be Amazon, downtime is an undesirable reality and jolts them no less, if not harder. Downtimes are caused by known factors including system upgrades or unknown factors such as application, server, or storage system failure. A Cisco study estimates the cost of an average mean time to resolution (MTTR) of downtime in the U.S. at $402,542. To shorten MTTR or outrightly eliminate downtime, Infolob recommends building a maximum availability architecture that brings resiliency to the enterprise IT infrastructure. Previously, organizations had to design and implement Maximum Availability Architecture (MAA) themselves, which was never adequate. Infolob observes that Oracle was among the first ones to identify business challenges caused by downtime and released Engineered Systems such as Zero Data Loss Recovery Appliance (ZDLRA), Exadata Database Machine, and Database Appliance (ODA) as part of its Oracle Maximum Availability Architecture (Oracle MAA). Oracle MAA is now a set of best practices methods that have evolved over the past 25 years based on proven high-availability architectures with end-to-end validation and expert user community feedback. These best practices remove infrastructure designing complexities, extract maximum availability from minimal system resources, and facilitate duplication of an ideal infrastructure design so that it can be swiftly installed in other business areas. Moreover, an MAA saves on maintenance costs owning to reduced system requirements.Oracle MAA expands across the entire technology stack including databases, application servers, collaboration suites, and grid control. Following are a few key benefits of considering Oracle Maximum Availability Architecture:
Oracle Cloud MAA Pioneering Agile Maximum Availability Architecture (AMAA)Oracle MAA best practices bifurcates high availability (HA) architectures into four reference architectures designed to match different requirements of enterprises of all sizes and domains. They are: Bronze, Silver, Gold, and Platinum. These four reference architectures enable users to choose the level of high availability according to changing business needs, which in turn simplifies migrating database from lower HA-tier to higher, one hardware to another, or on-premise to cloud. Bronze MAA Reference Architecture: topology:single instance + backup; suitable for development, testing, productions databases; benefits: single instance with restart, online maintenance, and validated backup and restore. Silver MAA Reference Architecture: topology:High availability + backup; suitable for production and departmental databases; benefits: active clustering and application continuity. Gold MAA Reference Architecture: topology:High availability + disaster recovery + backup; suitable for mission critical databases; benefits: physical replication and comprehensive data protection. Platinum MAA Reference Architecture: topology:zero data loss and zero downtime; suitable for business and mission critical databases; benefits: logical active replication and advanced HA options. When an existing Oracle MAA is extended to the cloud, it paves way to agile maximum availability architecture, creating following options to leverage additional Oracle products:
In addition to the three additional products that become available in AMAA, following two add-ons can be considered: 4.Oracle CASB: Cloud Access Security Broker for Applications and Workloads
5.Oracle Cloud Management Services: Efficiently monitor MAA
ConclusionBusinesses’ primary objectives are to satisfy customers and make profits. These objectives are severely affected due to system downtime, planned or unplanned. Oracle Maximum Availability Architecture (MAA) is a suite of smart systems and best practices methodology that have evolved over the past 25 years to protect businesses from system downtime. And now, Oracle Cloud MAA is coining the term Agile Maximum Availability Architecture (AMAA), facilitating several new features to strengthen data management, security, and monitoring. For more information: [email protected] What is Oracle Maximum availability Architecture?Oracle Maximum Availability Architecture (MAA) consists of a set of best practices blueprints for the integrated use of Oracle's High Availability (HA) and Disaster Recovery (DR) technologies that ensure this level of availability.
Which two are objectives of Oracle's data management strategy?Provide high availability and disaster recovery. Use data in a growing variety of apps, analytics, and algorithms. Ensure data privacy and security.
Which technique is used for high availability of Oracle Database?Oracle Real Application Clusters (RAC) enables multiple instances that are linked by an interconnect to share access to an Oracle database. This enables RAC to provide high availability, scalability, and redundancy during failures.
How will you configure high availability for an application in an Oracle cloud infrastructure region with a single availability domain?How will you configure high availability for an application in an Oracle Cloud Infrastructure region with a single Availability Domain? Setup your application across multiple compartments. Setup your application across multiple Fault Domains. Divide region into multiple subregions.
