Q. Is VPN or MPLS connectivity supported?
Yes, both are fully supported.
Q. Can KeyInfo assist with migrating to a cloud environment?
Certainly! This is what we specialize in, and why our clients partner with us to do with them.
Q. What is the difference between horizontal & vertical scaling and why does it matter?
One of the biggest features of the cloud is the ability to scale. There are different ways to accomplish scaling. One is vertical scaling and the other is horizontal scaling.
Vertical scaling can essentially resize your server with no change to your code. It is the ability to increase the capacity of existing hardware or software by adding resources. Vertical scaling is limited by the fact that you can only get as big as the size of the server. Generally, this means adding more memory, disks, and/or processors to your existing server(s). Problem that comes up with this method is, you will eventually fill up your server(s), and you can no longer add resources.
Horizontal scaling affords the ability to scale wider to deal with traffic. It is the ability to connect multiple hardware or software entities, such as servers, so that they work as a single logical unit. This kind of scale cannot be implemented at a moment’s notice, since the code that runs on these ‘nodes’ needs to be aware of this method to be able to take advantage of it.
Q. When is it appropriate to run on private, public, or hybrid clouds?
The reasons for using a private cloud are cost reduction, enhancing service quality, and, more importantly, reducing the time it takes to deliver what users demand. Public cloud mostly benefits web applications that are bursty or highly seasonal, as well as disposable environments such as testing environments. Hybrid solutions are often used when a company’s private cloud wants to use public cloud as a failover platform, or for scaling out for peak loads.
Q. Can KeyCloud be used for backup or disaster recovery?
Yes, and those are not mutually exclusive; we can do both at the same time.
Q. What are some of your IaaS IBM i Cloud features?
Zero downtime backups, redundant SAN storage, high performance storage, secure connectivity (Private connections, MPLS enabled, Fiber Network), personal onsite engineers, enterprise grade vertical architecture for quick and dynamic granular scaling as business and capacity needs grow.
Q. How is Zero Downtime backup achieved?
Utilizing IBM’s full system flash copy manager to take backups from a cloned snapshot of the running LPAR.
Q. What methods of backups do you have available?
BRMS: Backup Recovery Media Services
Q. Do you have a test environment that supports V5R4M0?
Yes, we can test and validate V5 environments to ensure compatibility when upgrading to V6 or greater.
Q. How do you size for production use?
Using a series of tools, including MPG, to model current workload performance.
Q. What media is used for backups?
Virtual Tape Library (VTL) and optionally LTO tape.
Disaster Recovery as-a-Service
Q. What should I back up for sufficient disaster recovery?
The goal should be everything! Just your data isn’t enough. Your entire infrastructure – SAN, NAS, servers, laptops – all contain vital production data. Be sure to collect application & OS configuration files, hypervisors, end-points, the more the better!
Q. Do I need to provision the same hardware for full disaster recovery?
No. All KeyCloud DR products use advanced recovery technology which allows the restoration of an entire system to completely different make/model of hardware.
Q. How fast will I recover from a disaster?
DR processes take time – this period is known as RTO (Recovery Time Objective). KeyCloud DR products can help you save significant time. We use disk imaging which captures your entire application stack, so you won’t be reinstalling operating systems, reconfiguring applications or restore data.
Backup and Recovery as-a-Service
Q. Where should I back up my data?
Storage choices are plentiful, and the choice depends on many factors: compliance, business policies, production cycles, and more. As DR experts, we recommend following the industry standard, the 3-2-1 rule: maintain 3 copies of your data stored on at least 2 types of storage media with at least 1 copy stored offsite.
Q. How often should I back up?
Frequent backups ensure you lose less data, however, this practice requires more storage. The uncertainty around the period of time between backups is called RPO (Recovery Point Objective). Weigh your options and find a balance between lower costs vs. shorter RPO. KeyCloud DR products include some smart backup features which reduce storage requirements and provide built-in deduplication and compression tools to maximize your storage and network usage.
