Containers enable the development of fault-tolerant applications by running multiple microservices independently. In the event of a failure, the issue is confined to the affected container, preventing it from impacting other containers. This isolation boosts the overall resilience and availability of the ...
Storage virtualization is the pooling of physicalstoragefrom multiple storage devices into what appears to be a single storage device or pool of available storage capacity. A central console is used to manage the storage. What is meant by storage virtualization? Storagevirtualizationor virtualized stora...
Disk mirroring, also known as RAID 1, is the replication of data across two or more disks. The term "disk mirroring" is sometimes used in a broader sense to describe any type of disk replication, but in most cases, it is meant within the context of RAID 1. Disk mirroring ensures that...
Fault Tolerance: The decentralized model of RPC services makes them resistant to outages. If a node is brought down, another will replace the service. This reduces downtime and ensures consistent availability. Challenges include: Latency: If not set up properly, decentralized RPC services can introd...
Where is the client? Better Software Architecture Which Theory Fits the Evidence? why do theory p and theory d matter? belief drives behaviour so which theory fits the evidence? d is for “d’oh! we should have gone with p!” Interlude: The Programmer’s Dilemma Project Management acts...
For enterprises, one of the most important production workload requirements is predictable and consistent performance to ensure business continuity. This requirement is backed by explicit commitments to service-level agreements. To be truly effective, both thePaaS and information-as-a-service (IaaS)laye...
Partition-tolerance Distributed systems designed for fault tolerance are not much use if they cannot operate in a partitioned state (a state where one or more nodes are unreachable). Thus, partition-tolerance is always a requirement, so the two basic modes that most systems use are either Avail...
For the maximum recorded MTTR of 30 days, this is a function of CircleCI’s dataset cutting off recovery at the 30-day mark – not meant to indicate that recovery is occuring in 30 days. The interesting data here is not the minimum time or the maximum time, but the median time to re...
Disaster recovery (DR) is one facet of the overarching business continuance plans devised and maintained by the various lines of business within an organization. An effective disaster recovery plan mitigates the impact that unplanned—or even planned—outages of mission- and business-critical systems ...
