ALS is usually a written agreement between a supplier and a customer regarding certain services and/or products (see Figure 1). In addition to the description of the services to be provided, an ALS also lists the rights and obligations of the supplier and the customer with respect to the agreed level of quality (level of service) of the services and/or products (services) to be provided.  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. A service level contract is an agreement between two or more parties, one being the customer and other service providers. It may be a formal or informal legally binding “treaty” (for example. B internal relations within the department). The agreement may include separate organizations or different teams within an organization. Contracts between the service provider and other third parties are often referred to as SLAs (wrongly) – the level of service having been set by the (main) customer, there can be no “agreement” between third parties; these agreements are simply “contracts.” However, operational agreements or olea agreements can be used by internal groups to support ALS.
If an aspect of a service has not been agreed with the customer, it is not an “ALS.” However, a supplier must put in place a price tag for the use of its facilities. To create an ALS, it must know what capacity is required to provide the desired level of service. In addition to ALS, SeLA (Hillenius) is manufactured. In addition to the service, the desired customer experience is also recorded. The advantage of this supplement is that it is based not only on performance indicators, but also on the customer experience. This experience can usually be determined by the core value of an organization. The client chooses an organization for a specific reason. If the basic value (promise) is not reflected in service delivery, the quality experience is reduced. A SeLA determines the technical, functional and relational quality. A web service level agreement (WSLA) is a standard for monitoring compliance with web services according to the service level agreement. It allows authors to indicate performance metrics assigned to a web application, desired performance goals, and actions to perform if performance is not achieved. The content of a service level contract must meet the customer`s requirements and wishes.
Of course, taking into account the possibilities that the supplier is willing to offer. Uptime is also a common metric that is often used for data services such as shared hosting, virtual private servers and dedicated servers. General agreements include network availability percentage, operating time, number of planned maintenance windows, etc. It is therefore very important to take into account not only the corresponding agreement on the level of service, but also the parental service contract and applicable terms and conditions. Of course, the main lines can be sketched. Typical topics regulated by most service level agreements: How many users can process this server? Can I run the SQL app database and an Exchange app on a computer? How many users can I deal with this Exchange server at the same time? Capacity planning in the Windows world is often pure gaming.
