[6] The Lambda team described Provisioned Concurrency as "ideal for implementing interactive services, such as web and mobile backends, latency-sensitive microservices, or synchronous APIs." [7] The Lambda Function URL gives Lambda a unique and permanent URL which can be accessed by authenticated and non-authenticated users alike. [8]
Lambda architecture depends on a data model with an append-only, immutable data source that serves as a system of record. [ 2 ] : 32 It is intended for ingesting and processing timestamped events that are appended to existing events rather than overwriting them.
For example, in a 50-user concurrent use license, after 50 users are logged on to the program, the 51st user is blocked. When any one of the first 50 logs off, the next person can log on. Concurrent licensing can be managed by the application itself or via independent software metering tools. Per seat licensing often imposes restrictions on the ...
Concurrent user licensing allows firms to purchase computer systems and software at a lower cost because the maximum number of concurrent users expected to use the system or software at any given time (those users all logged in together) is only a portion of the total system users employed at a company.
An execution of two concurrent processes where each process is waiting for another to change state (known as deadlock). An execution of a program can be described formally by giving the infinite sequence of program states that results as execution proceeds, where the last state for a terminating program is repeated infinitely.
Lambda Pinball" is a related anti-pattern that can occur in serverless architectures when functions (e.g., AWS Lambda, Azure Functions) excessively invoke each other in fragmented chains, leading to latency, debugging and testing challenges, and reduced observability. [4]
Serverless computing is "a cloud service category in which the customer can use different cloud capability types without the customer having to provision, deploy and manage either hardware or software resources, other than providing customer application code or providing customer data. Serverless computing represents a form of virtualized ...
Asymmetric price transmission (sometimes abbreviated as APT and informally called "rockets and feathers" , also known as asymmetric cost pass-through) refers to pricing phenomenon occurring when downstream prices react in a different manner to upstream price changes, depending on the characteristics of upstream prices or changes in those prices.
