There are actually many elements of such a vision that are working together. ACID and NoSQL are not the antagonists they were once thought to be; NoSQL works well under a BASE model, but also some of the innovative NoSQL systems fully conform to ACID requirements. Database engineers have puzzled out how to get non-relational systems to work within an environment that demands high availability, scalability, with differing levels of recovery and partition tolerance. BASE is still a leading innovation that is wedded to the NoSQL model, and the evolution of both together is harmonious. But that doesn’t mean they always have to be in partnership; there are several options. So while the opening anecdote is true in many cases, organizations that need more diverse possibilities can move into the commercial arena and get the specific option that works best for them.

This whitepaper defines provides a brief technical overview of ACID support in Aerospike. It includes a definition of ACID (Atomicity, Consistency, Isolation, Durability), and an overview of the CAP Theorem, which postulates that only two of the three properties of consistency, availability, and partition tolerance can be guaranteed in a distributed system at a specific time. Although Aerospike is an AP system with a proven track record of 100% uptime, this paper describes Aerospike's unique approach to avoiding network partitioning to also ensure high consistency. In addition, the paper describes how Aerospike will give users the option to support a CP configuration with complete consistency in the presence of networking partitioning by reducing availability.

As companies embrace NoSQL as the “next big thing,” they are rightly cautious of abandoning their investment in SQL. The question a responsible developer or IT manager must investigate is “in which cases are each of these technologies, SQL and NoSQL, the appropriate solution?” For example, cloud provider BigStep offered this assessment: “NoSQL is not the best model for OLTP, ad hoc queries, complicated relationships among the data, and situations when stability and reliability outweigh the importance of speed.” While that statement may be true of many NoSQL databases, c-treeACE is the exception. Its unique, No+SQL architecture offers the advantages of SQL on top of a robust, high-performance NoSQL core engine. In this white paper, you'll read five ways c-treeACE breaks the NoSQL mold in terms of: • Data Integrity • Availability and Reliability • Complex Data Relationships • Flexible Queries • Performance

The primary issue discussed within this paper boils down to two disparate database reliability models: ACID vs BASE. The first (ACID) has been around for some 30+ years, is a proven industry standard for SQL-centric and other relational databases, and works remarkably well in the older, yet still extant, world of vertical scaling. The second (BASE) has only recently gained popularity over the past 10 years or so, especially with the rise of social networking, Big Data, NoSQL, and other leviathans in the new world of Data Management. BASE requirements rose out of a need for ever-expanding horizontally scaled distributed networks, with non-relational data stores, and the real-time availability constraints of web-based transaction processing. While there are now more crossovers and negotiations between the two models, they essentially represent two competing groups, with Brewer’s CAP Theorem acting as the referee in the middle forcing tough decisions on each team.

Virtualization is rapidly changing the way business IT operates, from small local businesses to multinational corporations. If you are reading this, chances are good that your company is already taking advantage of virtualization’s benefits. Virtualization means that a single underlying piece of hardware, such as a server, runs multiple guest operating systems to create virtual machines, or VMs, with each of them being oblivious to the others. An administrative application, such as VMware, manages the sharing process, allocating hardware resources, memory, and CPU time to each VM as needed. And all applications look at this software construct exactly as if it were a real, physical server — even the VM thinks it’s a real server! Virtualization makes good financial sense. It enables a single server to offer multiple capabilities that otherwise would require separate servers. It includes native high availability features, so you don’t have to use any more complex clustering tools. This ab

Backup and high availability are both essential forms of protection that fulfill different roles within a data protection strategy. So which type of protection is right for different systems? According to recent analyst reports, experts recommend a blended approach that aligns data protection with type of data.1 By aligning data protection with data urgency, businesses can ensure higher levels of resiliency and reduce demands on internal resources.

Microsoft Azure is a public cloud platform featuring powerful on-demand infrastructure and solutions for building and deploying applications workloads as well as a wide variety of IT and application services. You can use Azure as a public cloud provider and as a hybrid extension to existing on-premises infrastructure. Organizations that use Microsoft solutions on-premises are able to extend their infrastructure and operational processes to Azure. With the growing popularity of Azure, today’s systems administrators need to acquire and strengthen their skills on this fast-growing public cloud platform. In this guide we explore the Azure public cloud platform with a focus on the Infrastructure-as-a-Service (IaaS) features. We cover general architectural features of the Azure cloud including geographic regions, availability zones, and Service Level Agreements (SLAs) attached to the core Azure IaaS infrastructure.

Imagine you’re running a factory but without a supply chain management system or industrial controls. Instead, you expect your customers to find and fix your delivery and quality problems. Sound ludicrous? Well, in many enterprises that’s the current “supply chain management” process for big and fast data. It relies on the lightly monitored dumping of unsanitized data into a data lake or cloud store, forcing data scientists and business users to deal with failures from data availability and accuracy issues.

As wattages increase in high-density server racks, providing redundant power becomes more challenging and costly. Traditionally, the most practical solution for distributing redundant power in 208V server racks above 5 kW has been to connect dual 3-phase rack PDUs to dual power supplies in each server. Although this approach is reliable, it negates a rewarding system design opportunity for clustered server applications. With their inherent resilience and automated failover, high-availability server clusters will still operate reliably with a single power supply in each server instead of dual power supplies. This streamlined system design promises to reduce both capital expenditures and operating costs, potentially saving thousands of dollars per rack. The problem is that dual rack PDUs can’t distribute redundant power to a single power supply. An alternative approach is to replace the dual PDUs with an automatic transfer switch (ATS) connected to a single PDU, but perfecting an ATS tha

The idea of load balancing is well defined in the IT world: A network device accepts traffic on behalf ofa group of servers, and distributes that traffic according to load balancing algorithms and the availabilityof the services that the servers provide. From network administrators to server administrators to applicationdevelopers, this is a generally well understood concept.
