Libby sucks and reminds me of amazon audible. I just find it confusing. And it uses WAY more background energy than Overdrive. Like what the hell are you doing back there? Especially when I've closed the program? What the hell?

But I'm not getting a choice in the matter cause they're gonna stop supporting Overdrive next year and I'm just very sad and frustrated over this.

Speaking on Friday at the Digital Switchover Launch in Kaduna state, he said the Digital Television experience will be of vital use to young Nigerians who…

1. Identical hardware is needed for high availability

Not anymore. Though gone are the days of IBM’s "Parallel Sysplex” with fault tolerance built on system firmware and even though hyperconverged solutions still require identical boxes to deliver high availability (unless complimented by a software appliance) today, where you have a virtual or physical Windows/Linux server, storage and network access you can deliver high availability with the same RPOs and RTOs in milliseconds but to/from dissimilar hardware.

2. Block-level, image based ‘availability’ will do

No and it never did. Using a block-level, image based backup tool to snapshot VMs every 5 mins consumes considerable system resource, is costly to scale and still only provides RPO and RTOs in minutes. Real time, byte-level replication can deliver more effective optimization of LAN/WAN with superior system performance so that failover can be automatic and genuinely instant.

3. High availability is only needed at enterprise organisations

Not these days. The larger the size of your company the greater the cost of downtimebut from your perspective that means nothing, minutes of downtime add up and in a competitive landscape can make the difference between winning and losing business, especially in the mid-market where IT services are delivered across locations and where the cost of downtime is significant enough to measure in seconds.

4. Hypervisor high availability is as good as it gets

No. Besides longer RPOs and RTOs with sync/recovery time in minutes, VMware or Hyper V high availability is restricted to its own hypervisor and out-of-the-box cannot detect application failure. In fact, application level high availability syncs/recovers immediately, provides cross-hypervisor compatibility, virtual to physical (and vice versa) support and detects application failure automatically.

5. High availability is expensive

You guessed it… not anymore. The liberation of high availability from identical hardware gives flexibility in how you provision it, redundant hardware is easier to refresh and allows for the repurposing (or tiering) of servers and storage. Virtualization drives the cost down again with public clouds like AWS, Azure and Arcserve Cloud offering different rates for cold and hot VMs so you only pay for high availability when you use it.

6. High Availability is a separate tool from backup

It’s a no. Arcserve UDP V6 allows users to manage their file based, image based and application level high availability from a single console. Users can turn on and off features according to priority and only pay for the features that they use; for mission critical services that would mean activating high availability as demonstrated here---->
