siliconindia | | July 201919MonitoringWhen the data is flowing between multiple clouds, monitoring the entire network will be a challenge. It would mean a remodelling of all the homegrown monitoring apps. Not to mention the retraining of the NOC team that supports the application 24x7 on different cloud environments. This means, companies opting for multi-cloud should be ready to invest in commercial monitoring tools that show all the data from different environments in a single dashboard so incidents can be resolved faster.Resources Public clouds will have a resource limit. Not all of them can provide the apps with as much computing power as they need in case of a disaster recovery situation, especially if the apps have to rely on the secondary provider when the primary is down. Additionally, the traffic has to hop between the networks of multiple clouds, meaning, important data has to travel via the same internet that is used to access cat videos. So bandwidth also ends up becoming a problem. The ideal way to run the app is always share the load between pods so traffic is distributed. Compliance Lot of mature public clouds will already have compliance in place. But some are not compliant to certain region's regulations, like the German Data Protection Act. Companies have to keep that in mind when they are choosing the public cloud providers and when they are distributing functions between the providers.Identical ServicesEach public cloud will offer a variety of preliminary services like data storage, email service etc. Companies need to evaluate the performance/SLA of each service before picking the right one for their apps.Data Transfer Latency & SecurityDuring multi-cloud deployments, data takes time to travel through different public networks (between clouds). This increases latencies, security concerns, and other inconsistencies. Companies have to prepare for the worst case scenario and would have to make a wise choice on what kind of data transfers can be compromised in these situations. Multi-cloud deployments are the definite next step when you want to promise your customers a 100 percent uptime. Even companies like Netflix have started using multi-cloud to make themselves available across the world. Implementing multi-cloud is not easy but when you want to scale rapidly and give better solutions to your customers, it is necessary.
