Alternative clouds are vulnerable to demanding buyers

Although big-name hyperscalers such as Amazon, Google and Microsoft dominate the cloud arena, other companies also believe they have a role to play. Vultr, OVHcloud, Linode, DigitalOcean, Bluehost and Scaleway, for example, don’t offer huge portfolios of cutting-edge products but their products focus on simplicity and low cost for smaller businesses with relatively straightforward requirements. […]

Is navigating cloud-native complexity worth the hassle?

Last month 7,000 developers traveled to Valencia to attend the combined KubeCon and CloudNativeCon Europe 2022 conference, the event for Kubernetes and cloud-native software development. A further 10,000 developers joined the conference online. The event is organized by the Cloud Native Computing Foundation (CNCF), part of the non-profit Linux Foundation. The CNCF supports and promotes […]

Costlier new cloud generations increase lock-in risk

Cloud providers tend to adopt the latest server technologies early, often many months ahead of enterprise buyers, to stay competitive. Providers regularly launch new generations of virtual machines with identical quantities of resources (such as core counts, memory capacity, network and storage bandwidths) as the previous generation but powered by the latest technology. Usually, the […]

Cloud price increases damage trust

In general, the prices of cloud services either remain level or decrease. There are occasional price increases, but these are typically restricted to specific features; blanket price increases across product families are rare. Price cuts are often the result of improved operating efficiencies. Through automation, slicker processes, Moore’s law improvements in hardware and economies of […]

Cloud SLAs punish, not compensate

A service level agreement (SLA) is a contract between a cloud provider and a user. The SLA describes the provider’s minimum level of service, specified by performance metrics, and the compensation due to the user should the provider fail to deliver this service. In practice, however, this compensation is punitive. It seems designed to punish […]

The weakest link dictates cloud outage compensation

Cloud providers offer services that are assembled by users into applications. An outage of any single cloud service can render an application unavailable. Importantly, cloud providers guarantee the availability of individual services, not of entire applications. Even if a whole application becomes unresponsive due to a provider outage, compensation is only due for the individual […]

Cloud generations drive down prices

Cloud providers need to deliver the newest capability to stay relevant. Few enterprises will accept working with outdated technology just because it’s consumable as a cloud service. However, existing cloud instances don’t migrate automatically. Similarly to on-premises server infrastructure, users need to refresh their cloud services regularly. Typically, cloud operators prefer product continuity between generations, […]

Why cloud is a kludge of complexity

The cloud model was designed to be simple and nimble. Simple and nimble doesn’t necessarily mean fit for purpose. Over the past decade, new layers of capability have been added to cloud to address its shortcomings. While this has created more options and greater functionality, it has also meant greater complexity in its management. Today, […]

Flexibility drives cloud lock-in risk

Vendor lock-in is regularly levied as a criticism of cloud services. But the reality of IT is, there has always been lock-in. Even before cloud, enterprises were locked into hardware, operating systems, database platforms, data centers and network providers. Practically, the lock-in challenge with cloud isn’t that moving from one location or platform is not […]
