Function as a service fusion deployment

A system, comprising:

• a processor;
• and
• a memory coupled to the processor, comprising instructions that, in response to execution by the processor, cause the system to perform operations, comprising:
• determining that a first containerized function of a group of containerized functions invokes a second containerized function of the group of containerized functions, wherein the first containerized function comprises a first container hosting a first function, and wherein the second containerized function comprises a second container hosting a second function;
• identifying a first number of instances of the first containerized function, wherein the instances of the first number are configured to be executed;
• identifying a second number of instances of the second containerized function, wherein the instances of the second number are configured to be executed, and wherein the first number of instances differs from the second number of instances;
• determining a first cost of executing the first number of instances of the first containerized function, and the second number of instances of the second containerized function, wherein the first cost comprises a first computer memory cost, a first computer storage cost, and a first service level agreement violation cost;
• determining a second cost associated with executing a third number of instances of a third container that comprises the first function and the second function, wherein the third number of instances corresponds to whichever of the first number of instances and the second number of instances is greater, and wherein the second cost comprises a second computer memory cost, a second computer storage cost, and a second service level agreement violation cost;
• in response to determining that the second cost is less than the first cost,
• executing the third number of instances of the third container,
• directing a first call to invoke the first function to the third number of instances of the third container, and
• directing a second call to invoke the second function to the third number of instances of the third container.
