Security – All security measures taken by the service provider are defined. This is usually the development and consensus on antipoaching, computer security and confidentiality agreements. The purpose of this ALS is to define the requirements of the SaaS service in the sense of: These systems and processes are often controlled by specialized third-party companies. If this is the case, it is necessary that the third party is also involved in the AES negotiations. This will allow them to obtain details of the levels of service that should be monitored and explanations on how to prosecute them. Monitoring and Service Report – This section defines the reporting structure, follow-up intervals and the parties involved in the agreement. A Service Level Contract (SLA) defines the level of service a customer expects from a provider and defines the metrics on which that service is measured and corrective actions or penalties, if they exist, if agreed service levels are not met. As a general rule, SLAs are located between companies and external suppliers, but they can also be between two divisions within the same company. Error rate: account or percentage of errors in important benefits. Production errors, such as incomplete backups and restorations, coding/redesign errors, and missed delays, can be included in this category. Because applications are moved from dedicated hardware to the cloud, they must reach the same level of service, or even more sophisticated than conventional installations. SLAs for cloud services focus on data center features and more recently include network features (see Carrier`s Cloud) to support end-to-end SLAs.
 Cloud providers are more reluctant to change their standard SLAs because their margins are based on providing goods services to many buyers. However, in some cases, customers are able to negotiate terms with their cloud providers. However, this is the case where an agreement on the level of service may take the form of a legal or informal contract or be part of a contract. Thus, a service level contract may be included in a contract, but a contract is not necessarily a service level contract. Many companies prefer SLAs that are not part of the contract itself, as this allows for a simpler review.
