A method at a computing device acting as a switchboard between an electronic device and a device to be updated, the method including receiving, at the computing device, a connection request from the electronic device, the connection request including an identifier for the device to be updated; receiving, at the computing device, a connection request from the device to be updated; associating, at the computing device, the connection request from the electronic device and the connection request from the device to be updated; forwarding, at the computing device, a message from the device to be updated to the electronic device that update conditions have been met; forwarding, at the computing device, a message from the electronic device to the device to be updated to start an update process; and forwarding, at the computing device, update status information from the device to be updated to the electronic device.

Provided is an application deployment method, including: receiving an application blueprint (S1) including at least two different sub-blueprints; and deploying an application instance on a hardware device in a cluster according to the application blueprint and external capabilities provided by all deployed application instances (S2), with a sum of the external capabilities provided by all the deployed application instances being greater than or equal to the total external capability of the application. The present disclosure further provides an application blueprint generation method, a microservice platform, a communication terminal and a computer-readable medium.

Methods are described herein for creating and installing software updates which may be rolled back, without requiring large processing capabilities and/or large storage capacity at a device. Delta software updates are determined comprising differences, on a bit-level, between a first version of the software and a second, updated, version of the software, and metadata defining how to apply the differences. Methods of performing a rollback-capable update at a device are also described herein.

A control node can be automatically deployed at a remote location according to some examples described herein. In one example, a system can automatically set up a control node at a remote location by performing various operations. The operations can include interacting with the remote location to deploy an instance of the control node at the remote location. The operations can include providing a configuration script to the remote location for use by the instance in configuring one or more managed nodes. The operations can include providing connection information to the remote location for use by the instance in establishing a network connection to the one or more managed nodes. The system can then initiate a configuration process in which the control node establishes the network connection to the one or more managed nodes and then configures the one or more managed nodes in accordance with the configuration script.

A method of reporting differences between a plurality of computing cluster configurations for executing containerized software applications may comprise routinely retrieving, at preset time intervals, cluster configuration files stored at computing clusters for configuring the computing clusters for execution of a containerized software application, receiving a user selection of a first cluster configuration file and a second cluster configuration file within the stored cluster configuration files, and comparing the first cluster configuration file and the second cluster configuration file. The method may also include displaying a difference between the first cluster configuration file and the second cluster configuration file resulting in the first cluster configuration file configuring one or more computing clusters for execution of the containerized software application differently than the second cluster configuration file configures one or more computing clusters for execution of the containerized software application.

A method for processing a query for data stored in a distributed database includes receiving, at an edge device, the query for data stored in the distributed database from a query device. The method includes causing, by the edge device, the query to be stored on a dynamic ledger maintained by the distributed database. The method includes detecting, by the edge device, that summary data has been stored on the dynamic ledger. The method includes generating, by the edge device, an approximate response to the query based on the summary data stored on the dynamic ledger. The method includes transmitting, to the query device, the approximate response.

A data processing system implements obtaining a set of input parameters associated with an update to be deployed to a plurality of server farms of a cloud-based service, wherein each server farm includes a primary replica configured to handle user traffic and a disaster recovery replica configured to handle user traffic responsive to a failure of the primary replica; determining temperature information for each of the server farms, ranking the server farms based on the temperature information to determine an order in which an update is to be deployed to the server farms; iteratively deploying the updates to the primary replicas of the server farms according to the ranking until an deployment threshold has been satisfied; and iteratively deploying the updates to the primary replicas of server farms for which the primary replicas have not yet been updated and to the disaster recovery replicas of the server farms.

A method, computer system, and a computer program product for deploying a plurality of microservices across a service infrastructure having a plurality of resources is provided. The present invention may include determining at least one dependency of the plurality of microservices. The present invention may include for each resource of the plurality of resources, determining an outage distribution descriptive of an availability of the resource with respect to time. The present invention may include based on the outage distribution associated with each resource and the at least one dependency of the plurality of microservices, determining a deployment configuration of the plurality of microservices across the resources of the service infrastructure.

Methods, systems, and devices for providing for providing computer implemented services using managed systems are disclosed. To improve the likelihood of the computer implemented services being provided, a subscription based model may be used to manage the managed systems. The subscription based model may provide for automatic configuration of and software deployment to any number of managed systems to provide subscribed to solutions to various users. To manage subscriptions, a highly available management service may be provided to users. The management service may allow users to select desired services. Once selected, the management service may automatically modify various managed systems to provide the subscribed solution.

Methods, systems, and devices for providing for providing computer implemented services using managed systems are disclosed. To improve the likelihood of the computer implemented services being provided, a subscription based model may be used to manage the managed systems. The subscription model may utilize a highly accessible service to obtain information regarding capabilities of managed systems to present information regarding all potential solutions that the managed systems may provide. By presenting users with such information, the users may not need to be well versed in the underlying hardware and software components necessary for the solutions to be provided. As the hardware components of a managed system are changed over time, the compatible solutions may be continuously updated so that users may be continuously appraised of possible solutions that may be provided using the managed systems.
