SLA@SOI

The barriers to cloud adoption are heavily documented across the internet. In this blog post, we examine some of the main solutions put forward by the SLA@SOI consortium in addressing the issue of data security…

SLA@SOI has developed a scheduler to help better deliver an SLA-enabled infrastructure. It allocates requested virtual machines to the most appropriate physical machines taking SLA specifications and data center policies into account. Read on to find out more…

The Future Internet constitutes the next major paradigm to support integration, interrelation and inter-working across the Internet of Services, the Internet of Things and the underlying technology cloud platform. Service Level Agreements (SLAs) are of crucial importance for securing the success of the Future Internet so that services in there become dependable and tradeable.

The SLA@SOI reference architecture for an integrated SLA management framework has been published in the Journal of Internet Engineering. The full article “A Reference Architecture for Multi-Level SLA Management” can be downloaded here.

Check out the latest issue of the Projects Journal for an article dedicated to the challenges that SLA@SOI is tackling, providing new service opportunities for consumers and providers alike. The article has been featured stand-alone and is also available online as part of the entire magazine issue.

SLA@SOI and RESERVOIR have been actively collaborating together with the aim of investigating and pursuing the integration of their respective technologies as part of the NEXOF Reference Architecture initiative. One of the outputs of this work has been a technical report that details how cloud standards, such as OCCI, can be used to support the [...]

As part of a Service Level Agreement (SLA), a service provider and its customer agree on non-functional or Quality of Service (QoS) requirements, which may be part of the pricing model. Predicting service quality attributes before service run-time helps to specify feasible SLA parameters and to consolidate efficient resource utilization with guarantees on QoS metrics. [...]

Over the last few years, several approaches have been developed to support the monitoring of SLAs. Typically, these approaches collect events during service executions and use them to check whether the properties of service provision as specified in an SLA are satisfied. Such approaches provide state of the art mechanisms for performing the basic checks [...]

In recent years, significant advances have been made in SLA management. This progress has largely focused on the building pieces necessary to create the communications, interactions and corresponding flows required for SLA management. However, to be truly useful, support for the business aspects and terms required in the real business world also need to be [...]

Service-Oriented Architecture (SOA) represents an architectural shift for building business applications based on loosely coupled services. In a multi-layered SOA environment the exact conditions under which services are to be delivered can be formally specified by Service Level Agreements (SLAs). However, typical SLAs are just specified at the top-level and do not allow service providers [...]
