Frost & Sullivan Report: In-Memory Computing Yields Real-Time Insights from Big Data
Perhaps the number one imperative in the business world today is to capture all data that is relevant to the organization, from all available sources, and put it to work to support business objectives. Companies need to answer questions in order to more effectively run their businesses. Businesses are increasingly finding those answers through analytics. Analytics is the science of examining raw data in order to discover meaningful patterns in the data and draw conclusions from it. Analytics also describes the software and methods used to understand data. Organizations generate and collect data to gain insights into the behavior of customers and competitors, and into their own financial and operational performance, then leverage those insights to make more accurate predictions and smarter decisions.
Using In-Memory Data Grid to Bridge the Cloud
A major challenge in moving applications from on-premise datacenters to public clouds is the reluctance to store sensitive data on the cloud, for various reasons: perceived lack of control over the storage, security concerns or non-compliance issues when data is stored beyond the enterprise's boundaries, or the need to store the data on-premise for other internal applications to access. A possible approach in such a scenario is to use a hybrid architecture where the bulk of the customer-facing application is moved to the public cloud, allowing it to leverage all the cloud’s advantages (scalability, cost, redundancy, DR, etc.), while the data store continues to reside on-premise.

Scale Up vs. Scale Out
This paper discusses the difference between multi-core concurrency (often referred to as the scale-up model) and distributed computing (often referred to as the scale-out model). While the two models seem similar, in the practical sense they are very different. Only the scale-out model enables leveraging the power of multiple machines while also reducing failure and downtime incidence. However, this approach can also involve increased system overhead. So, is it possible to choose between the two approaches? What factors should be considered? And how does the evolution of multi-core technology affect the need to choose?
NoCAP: Or, Achieving Scalability Without Compromising on Consistency
According to the CAP theorem, it is impossible for a distributed system to have all three CAP properties – consistency (C), availability (A), and partition tolerance (P) – necessitating a choice of only two: Some suggest choosing AP and compromising on consistency. Others suggest CA as a better set of tradeoffs. This paper presents the argument that it is not necessary to completely give up partition tolerance by choosing CA, or consistency by choosing AP. Instead of viewing each CAP property in absolute terms and selecting only two, we can adopt a more relaxed approach that applies various degrees of all three, and compromise on the degree in which we apply each property based on the application’s business requirements. In other words, address the most likely failure and network partition scenarios, and compromise only in areas where they are less likely to occur. A common GigaSpaces clustering topologies is used as a reference for this model, with a detailed illustration of how the topology applies to all three CAP properties.
Achieving Read/Write Scale Without A Complete Rewrite - A Customer Case Study: Avanza Bank
Many applications are built with layers upon of layers of development, with relational databases at the heart of the system. Scaling these systems is extremely challenging, leading many organizations to take the easy route – simply paying more for higher-end hardware and databases. Today, we have reached the point where this approach often does not work, and is simply too expensive to maintain with the advent of cheaper, more scalable alternatives. The case of Avanza Bank presents an excellent example of how it is possible to turn an existing online banking application into a new site that is designed for read/write scaling.

Real-Time Analytics for Big Data - An Alternative Approach
Real-time analytics are becoming part of mainstream system design, with high-profile companies such as Facebook sharing their design and implementation processes, proving that real-time is already a reality. However, most of these designs rest on assumptions that inherently limit the resulting systems, among t hem the idea that memory is unreliable, and that there is only one choice of database. This paper examines the proposition that these assumptions should be challenged, and that by changing them, inherent limitations of real-time analytics systems can be eliminated.
Virtualized CEP Services Integrated with GigaSpaces XAP
Complex Event Processing (CEP) is gaining ground in corporations across industry verticals. The first generation of business applications leveraging CEP have proven the advantages the technology offers beyond those that initially drew us to CEP in the first place. As a result a second wave, much broader in business requirements, are leveraging CEP as a core technology component. Its rapid expansion across the enterprise means that CEP technology must dovetail with the direction many IT organizations are moving towards, distributed computing and virtualization e.g. Cloud Computing. This paper focuses on how the limitations of today’s CEP engines are eliminated; creating “CEP Service Clouds” that natively take advantage of all that Cloud Computing offers
Scaling Spring Applications in 4 Steps
This paper is a brief guide to scaling Spring-based applications. It shows how to solve well-known problems that crop up when applications begin to scale out across multiple physical machines - a bottleneck in the data tier, a bottleneck in the messaging tier, a bottleneck caused by the tight coupling between business logic, data, and messaging, and a bottleneck caused by the limited methods that exist today to deploy and provision applications across multiple computers. We suggest a number of simple yet innovative steps, which leverage the idea of virtualization to help you release these bottlenecks, but do not require that you change your business logic code or otherwise re-work your application. The steps can be performed individually, as a targeted "cure" for each bottleneck, but together they form a holistic solution that leverages Space-Based Architecture (SBA) to enable true linear scalability for your application.

It is the result of a project carried out by GigaSpaces in 2008, to determine the basis for comparison between GigaSpaces Space-Based Architecture and the standard JEE Tier-Based Architecture. The project was conducted by Grid Dynamics, an independent consulting and engineering company, hired by GigaSpaces for that purpose.
From Only-SQL to NoSQL to YeSQL
It has now been a good couple of years since the various anti-SQL proponents have gained enough momentum to come together under the wide umbrella of the term NoSQL. And it is clear that we can never go back: the typical relational database architecture is clearly insufficient for today’s data-intensive applications, and the move to distributed architectures. But is the problem in the architecture or the query language? The two are not interchangeable, though frequently confused.
Should Web Apps "Just Say No" to SQL?
The recent inaugural get-together of the NOSQL community indicates a growing anti-SQL sentiment among developers. The NOSQL radicals are not alone: top companies in the Internet world, including Google, Amazon and Facebook, are basing their web applications on alternatives to the traditional SQL database. In this paper I'll briefly review what is driving this trend, survey alternative approaches to SQL databases, and discuss not only their benefits but also the risks and caveats for real-life web applications. Ending the paper is a thought exercize showing how Twitter's widely-publicized scalability problems could be addressed using non-SQL patterns
