IBM Cloud Sales Engineers assist clients in creating actions plans to help them resolve critical business problems.

Explanation

Object Storage is suitable for the backup of a database in cloud storage.

Explanation

A Multi-Zone Region (MZR) helps your load balancer appliances achieve high availability and redundancy. Use an MZR for core business applications that have stringent resiliency requirements. The MZR scales services based on events at a medium to high cost. An MZR provides these benefits: Consistent cloud services across the different zones Better resiliency, availability, higher interconnect speed between data centers for cloud platforms Infrastructure services such as IBM® Cloud Object Storage, and IBM Cloud load balancers

Explanation

Subnets are the foundational building blocks used to deploy cloud resources in your public cloud VPC. They are bound to a single zone and cannot span multiple zones or regions, which helps with security, reduces latency, and improves availability. Create multiple VPCs and subnets easily by using the suggested prefix ranges and preconfigured network security policies or design and define your own address prefixes and custom security policies. CIDR blocks 161.26/16 and 166.8/14 are both reserved and routed into every subnet. Read about our service endpoints available for IBM Cloud VPC. The default quota limit for the number of subnets that can be created within a VPC is 15.

IBM Watson Assistant helps you construct chatbots and virtual assistants for a spread of channels including mobile devices, messaging platforms, and even robots. IBM Watson Assistant allows you to use the power of Watson to bring a conversational interface to your solution. Your customers can interact with Watson Assistant using natural language conversation.

Direct area storage, also known as direct-attached storage (DAS), is as the name implies. DAS is a storage device which directly connected to your computer or server, if often connected to a single machine only. Some examples of direct attached storage are floppy disks, optical disc, compact discs (CDs) and digital video discs (DVDs), hard disk drives (HDD), flash drives and solid-state drives (SSD). DAS is often connected with single computing machine only so sharing capabilities are limited and poor. Block storage is highly available and resilient and will often include data encryption at rest and in transit. Block storage, is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. It can be attached to compute instance. Block Storage normally mounted onto only one compute node at a time. With block storage, you specify the size of the storage and pay a fee based on the size you provisioned. Block storage suitable for low latency workloads where consistently high speeds required. File Storage associated with Network Attached Storage (NAS) technology. File Storage organizes files in a hierarchy of named directories. The ability for File Storage to be mounted to multiple compute nodes at a time make it an ideal solution for common storage requirements. Object Storage enable you to store and access unstructured data anywhere in the world with a self-service portal backed by RESTful APIs. Object Storage supports exponential data growth and cloud-native workloads with built-in high-speed file transfer capabilities, cross-region offerings and integrated services. Use cases : Backup and recovery, Data archiving, Cloud-native application, AI and big data analytics.

Public gateway provide internet connectivity to the web server.

DevSecOps—short for development, security, and operations—automates the integration of security and compliance at every phase of the software development lifecycle, from initial design through integration, testing, deployment, and software delivery. Benefits of DevSecOps : Rapid, cost-effective software delivery.

You can use security groups to enact a set of IP filter rules that define how to handle incoming and outgoing traffic to both the public and private interfaces your instance. Use security groups when you order a virtual server. That way, your server is protected when it is first provisioned. Other Scenarios with solutions listed below : 1. Security scenario: Customers want granular control over traffic at an instance level (apart from network-level firewalls). However, at the same time, the costs of a shared hardware firewall can add up quickly if you need to protect multiple servers in different data centers. Solution: You do not incur extra charges for using security groups. You can use security groups for all virtual servers that need protection in any of our global data centers. 2. Security scenario: You want to avoid configuring firewall rules on each server separately. Instead, you want an easily manageable firewall solution that spans servers in different global data centers. Solution: Define N security groups for N different types of servers in your cloud workload. Manage all rules for a security group in one place. Manage the security group associations with the virtual servers.
