The ALS should set the overall objectives for the services to be provided. For example, if the objective of an external provider is to improve performance, reduce costs or provide access to skills and/or technologies that cannot be made available internally, WADA should say so. This will help the client create the service levels to achieve these goals and should leave no doubt to the service provider about what is needed and why. Another critical consideration is how the service provider is penalized if the service level guarantee is not respected. In most cases, this simply means that the service provider does not charge you for this period. In the next section, the overview of the agreement should contain four elements: a service level contract (SLA) is an obligation between a service provider and a customer. Specific aspects of the service – quality, availability, responsibilities – are agreed between the service provider and the service user.  The most common component of ALS is that services are provided to the client in accordance with the contract. For example, internet service providers and telecommunications companies will generally include service level agreements under the terms of their contracts with customers to define service levels of service level sold in plain language.
In this case, ALS generally has a medium-time technical definition between errors (MTBF), average repair time or average recovery time (MTTR); Identifying the party responsible for reporting errors or paying royalties; Responsibility for different data rates throughput; Jitter; or similar measurable details. Most service providers have standard SLAs – sometimes several, which reflect different levels of service at different prices – which can be a good starting point for negotiations. However, these should be audited and modified by the client and the lawyer, as they are generally favourable to the supplier. Service availability: The time available to use the service. This can be measured using the time window, z.B 99.5% availability between hours 8 a.m. and 6 p.m. and more or less availability at other times. E-commerce processes are generally extremely aggressive. 99.999 percent operating time is an unusual requirement for a website that generates millions of dollars per hour.
Today`s service providers do a much better job of providing customers with reports on bandwidth usage, operating time analysis and protocol management. However, there is still a very big difference between service providers, and you need to ask a number of questions. For example, does your service provider offer the most up-to-date online configuration for your evaluation? Do you receive daily, weekly or monthly reports based on your firewall, IDS or VPN protocols? What about ad hoc or personalized reports to allow you to perform a troubleshooting or forensic analysis? And will you be sure of backups of all configurations? Most service providers understand the need for service level agreements with their partners and customers. But creating could be discouraging, as if you don`t know where to start or what to lock up. In this article, we share some examples and models that will help you create SLAs. Set a good base number. Defining the right measures is only half the fight. To be useful, measures must be set at reasonable and achievable performance levels. In the absence of solid historical measurement data, you should be prepared to review and adjust parameters later through a predefined process specified in ALS.
