Abstract: Techniques are disclosed relating to storing location information about storage nodes in cookies. A cloud-based service may send location requests to an orchestration service that instantiated storage nodes included in a storage cluster of the cloud-based service. The cloud-based service may receive location information that identifies in which computer zone that a given storage node is located. The cloud-based service may store the location information in cookies at a metadata store that is shared among the storage nodes. The cloud-based service may receive, from a client node, a search request to identify ones of the storage nodes that store particular data. The cloud-based service may return a set of cookies corresponding to identified storage nodes. The set of cookies may enable the client node to determine whether there is a storage node that stores the particular data and is within the same computer zone as the client node.

Abstract: Techniques for automated defragmentation of licensed resources in a provider network are described. A defragmentation service in a provider network can detect the existence of intra-host fragmentation and/or inter-host fragmentation among host computing devices belonging to a host resource group of hosts dedicated to particular users. The defragmentation service can cause instances to be migrated to new locations within the host resource group to reduce or eliminate the fragmentation, allowing for hosts to beneficially be removed from the host resource group. The defragmentation service may determine which instances to be moved based on considerations involving software licenses associated with the host computing devices.

Abstract: This disclosure describes techniques for flexible maintenance windows for performing maintenance for instances. Using techniques described herein, a user of a service provider network may specify configuration data that relates to maintenance events of instances. A “maintenance event” is any event that relates to deploying instances and/or at least temporarily losing use of an instance. For example, a maintenance event may cause an instance to be deployed, re-booted, re-started, or replaced. According to some configurations, customers may specify one or more maintenance event windows for when maintenance is to be performed, as well as customize notifications that are provided to the customer about scheduled maintenance events. For instance, customers may create a maintenance window that specifies to perform maintenance on Tuesdays, between 2 AM-3 AM, and that notifications are to include information specified by the customer (e.g., through one or more tags).

Abstract: Systems, apparatuses, methods, and computer readable mediums for executing scripts within migrated hosts. The system enables a user to generate a task to execute a script on a host after the host has been migrated from a first data center to a second data center. This task may identify the host using a first ID of the host on the first data center. The host may be migrated to the second data center, with the host being identified on the second data center using a second ID. The system stores a correlation between the first ID and the second ID of the host. The system utilizes the second ID to retrieve a third ID for communicating with the host on the second data center to cause the host to execute the script on the second data center.

Abstract: Perovskites have high density of vacancies which absorb oxygen molecules and upon illumination, transform them into superoxide species which react with perovskites to decompose them, preventing use of these materials in many photo-applications. The present disclosure provides ways for improving the stability of perovskites in air ambient by doping perovskites with metals such as lead, cadmium, zinc, manganese, iron, cobalt, nickel, copper and tin which decreases the density of vacancies in perovskites and significantly increases the lifetime of perovskites. Perovskite solar cells containing inorganic and organic ions such as Cs+, formamidinium and methylammonium cations, Pb2+, Br— and I— with these metal dopants exhibit stable efficiency within a month of storage in air ambient with the relative humidity of 50%.
