1. Cloud infrastructure challenges
faced by carriers
To achieve lower TCO and enhance operational efficiency, carriers and enterprises are
migrating existing IT infrastructure and applications into virtualized clouds. Besides
the TCO savings of the internal IT, carriers are benefiting a lot from the new business
opportunities via multi-tenant public cloud. Cloud being adopted in VAS/BSS/OSS
systems effectively shortens the service deployment cycle and simplifies infrastructure
planning and management.
The migration into cloud also creates some key challenges:
1. Commercial and technical challenges for building and
managing a distributed, multi-vendor infrastructure
Typically, infrastructure is purchased and deployed layer by layer, with different
vendors for facilities, for hardware and for virtualization. This allows carriers to avoid
the problem of vendor-lock-in, but the resulting mix of vendors creates its own set
of challenges. Having multiple vendors for servers, storage, network and security
hardware, with various UNIX, Linux and Windows operating systems greatly increases
the difficulties in building and delivering a successful cloud platform and services.
2. Smooth migration to cloud data center without impact on
existing service
Building a new data center based on cloud computing concepts is easy, but converting
an existing data center is difficult and prone to errors which can cause service
interruptions. It is a key challenge for smooth migration of existing services to a cloud
environment without disruptions.
3. Different application scenarios require different infrastructure
resources
Many carriers provide IT service not only for themselves but also enterprises and
end users. Large enterprise, branch offices and SMEs have different demands for
infrastructure resources. Different applications, such as daily office use and mission-
critical applications also vary in requirements on infrastructure capabilities like storage
capacity and performance, network bandwidth, backup and HA solutions.
4. Supporting both fixed access and mobile access challenges
cloud services
The requirement for access to cloud services anytime, from anywhere is being driven
by the popularization of smartphones and tablet, including BYOD devices. Cloud
services can bring real value only if users can be effectively and seamlessly connected
to the cloud. Ensuring the user experience and service consistency in this type of
complicated environment will be a key prerequisite for efficient interaction between
users and cloud applications.

3.1 FusionSphere: agile and efficient cloud OS compatible with
OpenStack
Huawei FusionSphere cloud operating system is compatible with de-facto standard
OpenStack API, support multi-vendor hardware including server, storage, network and
security hardware, integration with third-party virtualization, storage virtualization,
network virtualization and security virtualization. In addition to being compatible with
OpenStack, Huawei FusionSphere supports more sophisticated features, which are
mostly beyond the capabilities of available version of open source OpenStack. These
additional features are required by carriers and enterprises for applications demanding
higher performance and more reliability. Huawei FusionSphere can significantly
enhance scheduling and management efficiency of IT infrastructure with full re-usage
of existing data center resources. As part of critical cloud service layer offering, Huawei
FusionSphere provides backup and disaster recovery, live migration, flexible resource
scheduling across data centers, SLA-based resource scheduling, intelligent bandwidth
scheduling, distributed storage and physical resource pools.
Huawei FusionSphere can be easily connected to the OpenStack resource management
and scheduling framework; making it a perfect solution for cloud transformation of
legacy data centers, as well as providing the IT infrastructure for new systems and
can be operated seamlessly within the OpenStack compatible architecture. Huawei
FusionSphere ensures sustainable development of data centers while avoiding the
problem of vendor-lock-in.

performance and high reliabilities in VM instance provisioning, clustered resource pool
management, and intelligent HA/FT scheduling. Huawei FusionManager is responsible
for enabling fully automated application image deployment, automated infrastructure
provisioning and configuration. With FusionManager carriers can flexibly define VM
CPU/Memory size, storage space and performance, L2/L3 network address, network
bandwidth and security rules, as well as the network topology and dependency
between distributed VM instances. FusionManager is also responsible for collecting
OAM FCAPS information from both physical and virtualized resources of Huawei and
other mainstream vendors, and provides unified portal for resource health monitoring
and timely troubleshooting.
Huawei FusionSphere also supports data center level storage virtualization and
"storage as a service" capability, which is called FusionStorage, thus enables standalone
SAN/NAS storage systems from multiple vendors to be consolidated as a unified logical
storage pool. The overall storage space utilization rate is improved dramatically, and
the storage migration across different SAN/NAS systems is minimized.
FusionNetwork based on SDN architecture is composed of user plane packet
forwarding part realized by vSwitch software over X86 server platform, and VXLAN
gateways for protocol encapsulation and decapsulation within each host. So that the
network resource provisioning and configuration of the edge network with direct
connection to VMs can be easily orchestrated with deployment of computing, storage
and even upper layer applications. Network traffic flow can be easily transferred
across multiple data centers. Carriers can reduce network management costs greatly
and enabled features like and cross-data center redundancy without manual network
configuration for VM migration across data centers.
3.1.1 Cloud service and API layer of FusionSphere
Huawei FusionSphere creates a single unified logical resource pool covering the entire
physical and virtualized infrastructure. It is capable of constructing an ultra-large-scale
logical cloud data center across physically distributed data center sites. It provides
optimal data center resource utilization and high energy efficiency by fine-grained,
cross-data center resource scheduling and uses SDN-based virtualized network traffic
engineering technologies, guaranteeing SLAs for different applications and the lowest
TCO for carriers.
For performance-sensitive critical applications or applications with special needs for
hardware platform RAS features in telecom and enterprise clouds, FusionSphere
supports direct scheduling and management of heterogeneous physical resources, and
provides related cloud services interfaces for cloud tenants and developers.
Service-independent active-active disaster recovery, active-standby disaster recovery
and backup are the key requirements to guarantee telecommunications service and
critical IT applications. With adequate bandwidth and network QoS, data center
disaster recovery can rely on storage snapshot or synchronous host replication
function based on Huawei FusionSphere. If a site fails, the recovery site in the pool
can immediately take over the workload of the failed site. For geographically separated
data center site where adequate bandwidth is not available (usually a transmission
distance greater than 100KM), the asynchronous disaster recovery mode and backup
mode can be used. Both HA (High Availability) and multi-vCPU FT (Fault Tolerance)
can be used to implement an active-standby disaster recovery system.

3.1.2 FusionStorage: Software-defined storage systems with innovative scale-
out engine greatly improve storage utilization and decouple application
deployment with complicated storage configuration
Currently, there are a variety of storage systems in the data center; typically the
storage systems and the applications are strongly bound; the HDD and SSD drives are
not virtualized and are not part of the global resource scheduling. Storage often lacks
unified management and has a low utilization rate. Huawei FusionSphere innovatively
uses a distributed storage engine– FusionStorage to unite internal SSD and HDD
drives, along with external heterogeneous SAN / NAS storage systems in a virtualized
scale-out storage pool. This pool has unified management and can provide scheduling
based on SLA. This software-defined storage system can improve the storage resource
utilization significantly and protect the existing storage system investment. Compared
to typical data center implementations, FusionStorage can increase utilization by 60%.
Huawei FusionStorage supports extensive storage features, including virtual SSD pool,
tiered storage, intelligent cache, thin provisioning and deduplication.

3.1.3 FusionNetwork: service-aware data center network based on SDN and
VXLAN creates a service-driven agile network
Huawei FusionNetwork utilizing a virtualized network based on SDN and VXLAN
can meet dynamic services needs, and has smart elastic scaling capabilities. It
automatically links network configuration management, virtual machines and
application deployment to create a very large layer 2 network across the data centers.
This simplifies application deployment and allows flexible resource scheduling. SDN
(Software Defined Network) includes virtual switch, a VSG (Virtual Service Gateway)
with virtual firewall and VPN capabilities and a centralized SDN controller cluster.
Huawei FusionNetwork can be decoupled from the physical network equipment,
supporting L2 ~ L7 network functions, VDC, VM live migration and HA. FusionNetwork
can adjust the bandwidth and routing policies of the WAN dynamically based on the
upper-layer services' demand. This can provide 60% -70% average bandwidth costs
reduction across the data centers.
3.2 FusionCube: superior-performance "cloud in a box"
converged infrastructure
Rapid deployment and expansion, along with unified management are highest
priority concerns of customers who want to quickly build enterprise private and
hybrid clouds, from data centers of branch offices all the way up to IT Hosting centers
offered by service providers or carriers. To support quickly and efficiently building
these platforms, Huawei offers the Huawei FusionCube converged infrastructure,
reducing implementation from weeks to hours. Based on a state-of-the-art distributed
FusionStorage storage engine, Huawei FusionCube significantly enhances the
performance of applications, typically more than four times better price-performance
compared to other offerings.

bottleneck between storage and computing. The result is optimized for IO-sensitive
enterprise applications, as well as for high-performance data warehouse scenarios.
Huawei FusionCube has also been validated and optimized for 3rd party middleware
and applications software. Unified and automatic management, rapid deployment,
efficient operation and maintenance are other important highlights of FusionCube.
Compared to other converged systems, FusionCube performance is better by a factor
of two, is more cost-effective by 4 times and reduces TCO by 50%. Typically, the pre-
installation time is just 130 minutes (46% saving compared with other converged
systems).
FusionCube creates a simple, powerful infrastructure and fully supports the OpenStack
open APIs and northbound management interfaces. OpenStack elastic computing,
object storage, virtual network, security, authentication, billing mode and image
management are supported, among others. This support of open interfaces means
that there is no vendor-lock-in and FusionCube can be connected to other cloud
platforms via standard OpenStack APIs. The converged cloud from different
vendors can be managed by a unified cloud OS management system or data center
management system which meets with the operational requirements of the carriers.
The integrated, modular FusionCube becomes the basic unit of data center one-stop
procurement and construction. It is especially suitable for urgent customer demand,
with short construction periods, such as for providing IT Hosting services by carriers.
Huawei FusionCube converged infrastructure is a compelling choice for new data
centers, expansion of existing data centers and even for branch office infrastructure
construction.
3.3 FusionAccess: seamless access to cloud services
The total number of smart devices in 2016 will reach 10 billion, far more than the
number of PC devices. The rise of smartphone, mobile broadband and BYOD has
blurred the boundaries between PCs and mobile phones, also blurring the boundaries
between personal equipment and business equipment. Many customers now require
access to a wide variety of cloud applications dealing with both business and personal
affairs through different terminals from anywhere. This is a huge opportunity for both
carriers and enterprises.
